    Unpleasant distortion on certain notes.

    I have been having an issue with my 5E3 where it has a very nasty sounding distortion but only on or near A, or when playing an A chord. It does not happen when I first turn on the amp but it gets...

    Sorry I did not phrase my question well. I'm not worried about the 16V, I just wondered if it was a problem that a normal 5E3 circuit would instantly discharge to zero. Maybe that circuit already has...

    It's a 5E3. No mods that I'm aware of.

    Amp NOT retaining any voltage on the caps.

    Is the danger from amps holding onto their voltage something that always happens or something that happens sometimes? Mine goes to zero then slowly builds up to around 16VDC on the positive side of...

    Mine feeds back when the tone knob is cranked and it's really loud because you are jacking a certain frequency range way up and it makes that frequency feed back. I saw from your other thread you...

    Quick update. I finally broke down and totally disassembled the amp. I took the chassis out and took the speaker out of the cab and held it while I let the low E ring. The rattle is coming from the...

    I really thought that too but I went from a 20W speaker to a 50W tone tubby. I dunno the problem did start when I installed that speaker. I just got to put a 40W fender deluxe into that speaker and...

    I put a Hammond 1750E in to replace the really expensive MM tone clone I blew up. I am pretty sure now I did hook up the signal lead straight to ground and just let it burn out while I recorded the...

    Ya know what though I just realized, I had an issue a while back where the bolts on the OT got loose, one fell totally off and the xfmr was dangling. The ground wire on the secondary is soldered to...

    Ugh you are right I was just looking at that when you replied. I show an open circuit across the output of the OT. Stupid thing was working when I took it apart. At least I had output, maybe that was...

    When I say made a racket, it's making the tube rattle. The sound is coming from inside V2. Nothing comes out of the speaker. No hiss, hum, pop or noise of any kind as I was checking the pins. The amp...

    Rebuild finished, no output, no hum

    So I finally decided to recap and rewire my chassis of this home brew I bought a while back. It's all back together, nothing blew up. New pots, sockets, wire, caps. I have no output whatsoever. No...

    New info, the problem goes away after it warms up for a while. Do tubes behave this way? I'm leaning more toward the bad connections and wire dressing. I think I'm gonna gut the chassis and start...

    That makes a lot of sense. The wire in this amp is a total mess, all melted and tangled. I am thinking about ordering new caps and resistors and just redoing it. I always wanted an amp project. I...

    As volume goes up it gets slightly more crackly, but its bad at even low volumes. At some point the overdrive blends in with the crackle but it's still there. Tone does not have much effect on it. I...
  17. Crackling, worse with higher input, certain notes

    My 5e3 that I love too much to blow up is having yet another mystery problem. I have seen lots of threads on this issue but none of them have ever posted the solution.

    The crackle happens with...

    I finally got some time to look at the amp. I bought a new bolt to hold the xfmr in place. There are lots of places where insulation has melted off the wires. I don't know if something may have...

    Thanks for the reply. I am aware of the dangers of the caps holding onto the 300V, I don't touch anything until I let the thing sit for a couple days and check it with a meter. I never have rigged up...

    I bought a 5e3 clone from a guy, I don't know much about it, it seems to be built of quality stuff.

    It has worked like a hose for about 6 months, today I plugged it in and its making a loud static...

    Advice for salvaging old amps?

    I saw a couple guys talking about finding old radios and phono's and getting the iron, tubes and sockets out of them. I would love to try this for my first 5e3 build. I know a kit is recommended but...
