I had this ONCE, on a peavey CS power amplifier.. Pretty much exactly the same scenario as yours... The problem did arise again, about 2 years later... So i gave it another clean.. and again, fixed itself... On the 2nd "repair", i cleaned around each component and then tested again... I found it to be dirt around the potentiometers..... Well... thats what i believe, because as soon as i cleaned around them and removed the dust and grime.. thats when the problem was resolved.... And since the legs of the potentiometers are pretty closely placed to eachother, and dust can be partially conductive over time etc... I hoenstly believe it to be that...
That is some great insight, and I actually believe you are right!! That's the only thing that kinda makes sense. Thank you for commenting and sharing your experience!
Saturation problem thermal runaway that can also mess with the bias function as repairman and tech we all say dust is the number one enemy of All electronics it can cause serious damage to the whole amplifier the amplifier must stay cool to function efficiently and as intended! The heat sinks must stay properly cooled so removing all the dirt and filth solve your problem 👍 Also use some Deoxit contact cleaner in a spray can to clean the volume control potentiometers if volume control potentiometers are not moved for a while they can collect dust down inside the pots and they will lose contact connectivity between the wiper and the track of the potentiometer. It's just a suggestion❤ thanks for sharing✌️😁
@mainejason The potentiometers or /variable resistors or you can simplify a volume control is connected to the input of the amplifier. Which are connected to the op amp. If they are dirty corroded there will be bad connectivity between the wiper and the track. Also if you are interested I have a RUclips channel if you want to like subscribe and share and you can learn some stuff through me if you would like I'm a fabricator engineer tech and designer I build my own custom amplifier and boards among other things 💯💖🤗 if you wouldn't mind please like subscribe and share I believe we are a community here on RUclips and we all can help one another as well as learn from one another many blessings have a great day my friend
@mainejason I'm trying to reply to your post and RUclips is not allowing me to do so and I don't know why 🤔 so I'm going to try to reply and post it again if you don't get my second reply please let me know thank you so very much 😁💯✌️😁 I'm trying to tell you something in more detail about what I was expressing to you in my first post 😁

Sweet result, but as you said it's a puzzle. I wouldn't have thought that just cleaning the dirt would sort it unless maybe there was something conductive you hoovered away. Also, as you said maybe a cold solder joint you knocked back into contact with the nozzle? Loved the screw-removal jazz.
I agree with you on all counts. For now, I'm going with the old, "If it ain't broke.....(anymore)" 😆 I thought jazz seemed to fit the mood Thank you for your comment!

Great information, and it all makes perfect sense!!

Nice work! Don't you love it when a plan comes togehter?
Thank you for watching, my friend!
I do love it! Even when the plan is....no plan at all!!

Thank you for your comment!
пыль делала проблему!!!
I agree with you! I believe it was the dust.
Thank you for watching!
