Sexy O2, T&_A 675 (03) - Hurry Up, I Can'_t Go a Minute Longer Without a Dick in my Bitchy� Apr 22, · Common Tube Amp Malfunctions: My amp makes no sound. If your amp makes no sound, it is first important to define what you mean by “no sound.”. To that end, the first test you should perform is whether you can hear anything coming from the speakers. (This is, of course, after you have eliminated the possibility of trivial problems.)Estimated Reading Time: 8 mins.
Apr 29, · Fired up my Mesa TA 30 this week that I haven't played much in the last few months and am blown away by the versatility of that amp. It's got more great tones in it than any other amp I've played, even my Mark V. Am curious what other amps are out there that are considered versatile in terms of a variety of good, usable tones.
cause them to act that way. You can't match your tech's experience in general, but you CAN know a lot about how your particular amp might go bad. You can spend some time swapping in a tube known to have a bad section 1 and seeing what it does; a bad section 2 to see what controls work and how, a known microphonic tube, a hissy, noisy tube, etc.
Aug 13, · Many car amplifiers are incorrectly diagnosed and sent in for repair/returned because of incorrect hookup. Sometimes the amp itself really is at fault. Here are a few common problems and what can be done to troubleshoot, as well as fix them (my fixes are the most common. They are not definitive in any way. Your amplifier could have a completley different problem, though it isEstimated Reading Time: 5 mins.
Dec 31, · As I said earlier, I have not seen the amp., so I don't know what brand it is, but it takes seven of those tubes, not five. I don't know what band he plans to use it on (I don't know the exact frequency, but hopefully, the amp is broadbanded enough), but i'm guessing 75 meters. I don't know a thing about tubes, sweep tubes or sweep tube amplifiers.
Jun 10, · Jun 9, #6. I should further clarify. My OP is that you must crank the amp to get good tone. That, good tone can not be achieve without doing this. This is what I disagree with. I have found that yes to get the optimal tone with many amps, getting the volume around 4 .
May 02, · Hi there, I think this is kind of an interesting way of doing this. I am installing a Hertz Mille Pro (mpk , 4 ohm) component set-up into my 4runner and I need to pick an amp from my existing stash. I took the backs off all three amps and was surprised at what I saw. I guess largely.
Aug 09, · How many of you are running amps like DC, AQ, Crescendo, Sundown or the like wired to half ohm without problems? I know that there are some on here. Where yall at and have you had problems doing so or not?
May 18, · The suggestions about putting it on something instead of carpet is a good idea. This flap you're talking about is at the base of the trunk lid near the hinge I assume. That should be held down with plastic tabs once you're done wiring under it. The amp can be placed on top of it and there shouldn't be much contact with the seat up.
Oct 01, · St. Louis, MO. Oct 1, # regarding wire size, 8 gauge is fine for just the jl amp, but with both amps, 4 gauge is recommended. as for the heat, it sounds normal to me. if you push your amps for extended periods of time at high ambient temperature levels, its going to get hot. 1.
Apr 25, · I connect the amp to my PC's Center Subwoofer out with a RCA to mm cable. It gets hot even when it is not turned on. The red box is where it heats up. The amp can't really drive the shakers. It doesn't have the headroom. You should get something with an output of + Watts, and it should be rated for 2 ohm loads.
Apr 25, · I'm an engineer and I am building a tube amp. I don't need to build a tube amp, I don't need to have a tube amp, I am doing it simply because I want to. But I believe in building things as bulletproof as possible. So I would like to know, in extreme detail, what happens inside a tube amp when you hit it with a signal and no load is connected.
Oct 18, · You can't have a box with an amp in it. An amp is a flow, defined as current per second. Like, water might flow in gallons per minute, but when you say, “amps” you are already saying, “per second” (literally, amp-seconds per second). When an amp flows for an hour, that's an amp-hour. You CAN have a box with amp-hours in it.
Jul 28, · I'm using an ampeg b 25; 50 watt tube amp, I would usually warm it up on standby for about 10 minutes before playing. But after i play it for about half an .
Oct 16, · 1, Oct 14, #2. The most basic possiblity is the volume or balance controls are dirty/corroded. They could cleaned with contact cleaner. You could have one or more cracked solder joints. You could have bad internal components. Nobody on a message board will have a fix. It requires hands-on with the unit.
Oct 10, · HI everyone. I got a new amp from used guitar shop. It's Roland 20 orange. The problem is the overdrive jack ain't work. Before I buy it. I did test and it sound fine but when I take it home it.
Jul 30, · And Jaymz is right, some preamp tubes don't light well, but if you're not seeing any heat for sure you won't get any sound. They don't work cold. I had a heater wire come loose on my during a show and barely squeezed by based on the heat already in the head box. The amp was sounding pretty weak by the end of the set.
Re: woops, i left the amp on overnight. Being in the on position will wear out your tubes and stress everything, but in standby it can be on for a long time with no negative effect. I actually left an amp on standby for 3 months, and the tubes are still fine. It was my Gibson Goldtone which doesn't have a jewel light anywhere to be seen, and.
Aug 23, · Amp Getting Hot and Going Into Protection - This is my setup. I have a 12inch solobaric L7 powered by a kicker amp. I also have a kicker amp (4 channel) powering kappa perfect component in the front and kappa perfect 6x9's in the back. .
The amp will still work, but not as well. Why all this? Simple, a watt amp with two tubes removed doesn’t sound as good as the same model amp really made as a 50 watt amp with the correct transformer. The “10 times” audio factor is also the reason audio taper pots are used in guitars and amps to control powered audio signals.
Sep 19, · 2, posts. pm. Edit. Delete. Leaving a tube amp on 24/7 implies that it will be left on unattended. If one of the tubes fails and the amp is unattended this could cause a significant fire hazard IMO. I would NEVER leave my tube amps or preamp on 24/7 under any circumstances. gloriousunicorns.
These pesky noises can come and go or be triggered by certain notes. There are a few things that can make an amp “crackle” and I will try to give you guys some things to look at so you can try to diagnose the issue and possibly fix it yourself. On a vintage amp intermittent crackling can be caused by a .
Dec 10, · However, part of your set up made me realise that I wasn't thinking it through properly. Because my speakers are in the kitchen my train of thought was that is where the amp for zone 2 would also go. If I put the second amp in the same place as the first, my main amps remote can control that too. Turning on amp2 at the same time as amp 1 isn't.
Sep 25, · I have an SE5a amp. This is a 5 watt, single-ended valve amp that uses just one pre-amp valve (tube) and one power amp valve. If I change that pre-amp valve - an ECC83 (12AX7) - for a different make, I can hear the difference.
May 06, · Remember, voltage can kill a person if enough voltage is applied. An average wall outlet has a voltage of Humans can die from volts if applied correctly. But it isn't specifically voltage which kills, it's the current in proportion to the voltage which kills. Any fuse can make an amp look dead.
Apr 01, · 5. Connect the amp to a working pair of speakers. If your amp turns on but no sound comes out of the speakers, your overall setup may be the problem. Not all speakers are compatible with an amp. If your amp is still alive, it will respond when you connect it Views: K.
Jul 24, · Guitar amps are, no matter how you cut it, black boxes. You may think you have control over them, but when it gets down to it, you can’t really see inside the black box, and even if you could, there aren’t any moving parts. Electricity is largely non-mechanical. Or in other words, magic. And when the magic stops, most people think all they can do is resort to prayer. Or an amp technician.
Feb 15, · The 2A3 vacuum tube is a power triode capable of outputting W in a single-ended Class A configuration. In this project, the 2A3 power tube runs at a mA plate current with no signal applied and has a V plate voltage. The output transformer’s primary impedance is .
Dec 27, · One thing I like about tube amps is their repairability. Solid state amps in general, are designed to be less expensive and disposable. Some repair parts for solid state amps are no longer manufactured and symply don't exist. Someone can bring a tube amp to me and I can change the way it sounds without much difficulty.
Feb 05, · The HD uses the same dac and 4th gen class d amp which is very good. Dac is more than good enough for those great KEFs. A dealer telling you it’s a poor amp is an alarm bell for them trying to sell you something instead, to my mind, particularly if they don’t run that brand. Hifi is .
biasing power tubes can kill you if don't know what you are doing. There are lethal voltages in a tube amp. This is true on many amps (all Fender vintage amps) even when the power has been removed. Take your amp to a qualified amp tech to have the tubes biased and checked once a year.
Feb 03, · Cathode stripping can only occur in situations where thousands of volts hit the tube elements before this elements are warmed up. however, there is a detrimental effect that does occur when an amp is left in standby for long periods of time. That effect is known as cathode poisoning.
Jun 01, · This is where it all starts. You really cannot build what you can’t hear, just like you can’t cook what you can’t taste. If you don’t taste the difference, you can’t put it together. And when you do, then you kind of don’t look at the parts the same way. If you open up a Dumble amp, there’s Radio Shack stuff in there.
Aug 22, · Basically, he said that, if left powered up 24/7, they either die at some point in the first hours (infant mortality of sorts) or they basically last forever. I leave all of my equipment except turntable and tube amps powered up 24/7. Over the years, this has included a tubed DAC (Cal Audio) and three tube preamps (Jadis, CAT and Hovland).
Oct 26, · By changing your omhms your resistance will go up (switching from 2 to 4 ohm) or down (from 4 to 2 ohm). Less resistance means more power that can by put out (as you can see in the amp specsheet). More power means more heat. Inside your amp there is a part that changes the amp's internal voltage up (sometimes as much as V).
Mar 09, · Without the load the amp and the engine can easily be severely damaged, in the case of the amp by thermal runaway. "if an amplifier has no load to push; then where can the power, built up in the transformer go?" The amp technically has no "power", meaning watts, until it is fed a signal and has a load placed across its outputs.
May 31, · May 30, # Pull the HT fuse on the back panel and check it with a multimeter (you should read a short or near zero ohms if it's good). If it's popped, you quite likely have a problem with your power tubes. I was looking at my pix of my SB50 (which I sold some months ago) and I couldn't locate the mains fuse.
Apr 14, · My amp use to overheat like a bitch! I took 2 12v computer fans and wired them into the amps remote power source, so when the amp was on, so were the fans. Pointed the fans so the air blew over the amp and it worked perfect.
Dec 24, · This has been really helpful. I don't often get the oportunity to listen for extended periods, maybe X per week. I do however take min. once or twice a day, sometimes more, and for that short of time tended not to let the tubes warm up to much, and .
The phase inverter tube is playing an important for the clean headroom of your amp, and it should be replaced as often as the power tubes and for the exact same reason; clean headroom. The recitifier tube we keep longer than the power tubes as long as it is noise free and can provide a high enough bias current for the power tubes.
Jan 14, · Hell, the amp in the OP doesn't even have tube retainers on the power tubes, there is nothing to hold those tubes in place in case of a sudden landing. I buy (and occasionally sell off) vintage amps from the '40's through '60's that are not only expensive, but just plain irreplaceable; I couldn't just go out to the store and replace them.
For troubleshooting purposes, I always keep a couple of my old, worn tubes on hand. For my trusty '68 Twin, I carry a set of worn out s, a 12AX7, and a 12AT7, and they come in handy all the time. Starting with the power tubes, I replace each tube one by one, each time turning the amp back on and listening for the problem.
Sep 09, · The issue is the ~30º of movement the joystick has only creates ~V difference between the high and low output if the hall sensor. I can for example make the lowest value 1V and the upper limit V, 2V and V and so on. The arduino I'm using to take these voltages and talk to the computer likes a 5V difference between low and high.
Nov 04, · Posts. #5 · Nov 4, if an amp is designed to be 1 ohm stable, then its ok. running an amp not designed to do it can/will end up bad. there are some amps that can do.5 ohm, and a very few that can do B.
If the amp then powers up, you'll know the problem was one of the tubes. So then you'd just replace the tubes. If the amp doesn't power up with no power tubes, you'll have to go to a tech. Edit: Oh, and don't go poking around in your amp until you know what you're doing. High voltage tube gear can kill you dead, even if it's been off and unplugged.
Jun 15, · robertawillisjr said: ↑. Don't waste the energy. Turn on the amp and preamp for about 20 minutes or so to warm up before doing critical listening. Even if your units are in "standby" mode. This is what works best for me. I don't think it is a good idea to use .
Oct 01, · Changing tubes won't change power output. If you need that much more loud, it's time to consider a different amp or an external cabinet. Aside: I didn't even know you could find original 6L6s anymore. I gave the last set I had to a guiarist friend for his .
Q: Can I remove 2 tubes form my watt amp to make it 50 watts? Removing tubes causes operating voltages to rise in the amp and stresses the remaining tubes reducing their life expectancy. This can be very dangerous in a mid 70's Marshall that runs at v .
Jan 15, · Some other observations have had since posting is that popping would sometimes stop for longer periods of time maybe even mins before starting again. Also the volume doesnt effect the popping, i can hear it when it is on 0 and doesnt change much when i crank it up. I left my amp on for a couple of hours to see if it got any worse.
Dec 20, · amp just to familiarize myself with its operation and it's acting rather peculiarly. The supply pins read at +/- (+/- 9V) appropriatly and I'm running it as an inverting amp with feedback resistor of 10K and my input resistor of 1K and my signal into this. My + input is grounded as is pin8. Both offsets are open. So my gain should be The first.Sexy O2, T&_A 675 (03) - Hurry Up, I Can'_t Go a Minute Longer Without a Dick in my Bitchy�SweetBettyParlour - Spinosaurus x SweetBettyParlour Latina girl gets fucked by boyfriends friend Scandal Mohammed A Haseebfuck 18 A mature bbw with a gorgeous ass in panties washes the floor and then changes into a sexy outfit Hom Culona mostrando todo Hot Porn video Shapely beauties are hungry for that black pecker No Safeword - Chain Waterfall Top and Brief Set Sacandome toda la leche Bathing And Cumming
