I think you helped me with camera advice so message me if you need any amp repair advice. I've got a HRD III that is constantly trying to end its own torment and I've done a bunch of little things to it.
Absolutely, I've decided to accept my amp is just haunted when i hear reverb with the knob turned to zero.
I've had to reflow connections, replace load resisters, replace all the tubes and re-bias the amp. Broke out the schematics and went through test points and everything.
Its an awful little goblin amp and weighs 50 pounds but it was the very first big thing I bought when I started working as a teenager and I cant seem to let it go.
Same story with mine, i ended up getting one as a teen, then bought another for dirt cheap 7 years ago. Had some guy repair it in the past after tubes blew, ended up cutting a ground wire to V1. This amp always has a dirty character, then i picked up another and it’s clean and loud and completely managable.
My latest gremlin has been a tone that generates under a note i play that overpowers my highest notes with an inharmonic distortion. But that’s gone away the last time i played it.
Do you ever have odd volume behavior? For example, I'll turn it on one day with the clean volume around 2, it will be loud. Then another day I'll turn it on, settings unchanged, and it will be half volume and I'll have to bring it up to 3 or 4, which normally is enough to shake the drywall, just to get a normal level.
I have so many old tubes, I've considered turning them into Christmas ornaments by soldering a hook onto the feet. They're too cool looking to toss but are no good in the amp.
Life is also a lot better with an attenuator between the power out and the speaker.
Cant say i’ve had that particular problem, except for gain. This makes me think i have a problem in my preamp section.
I wish i could switch out tubes for 2 of my amps. But they got EXPENSIVE, especially cause i favored Sovteks cause they used to be the cheapest. Also all my amps are Sovteks so i thought it was funny
I’ve recently returned to wanting to get into guitar amplifier repair and design.
I have a pair of amps that i want to diagnose some particular problems and perhaps design a new pcb for or build out whole new ones

That sounds right. Amps are such annoying little fragile things arent they?

God the sovteks. I also like soviet watches and two of my interests are directly fucked from the war.
I mostly play acoustic stuff now, I have an alright manouche style guitar that I play more than most of my guitars now.
