Take care of yourself......I found in life nothing really means anything other then what you yourself can accomplish. Everybody else can go F themselves if they don't like it as long as you are righteous. People, especially women always think the grass is greener on the other side. Most are in for a rude awakening.
Those amps not only sounded great but they looked great too........I would start at the beginning. Check all your voltages and make sure they are what they are supposed to be. Clean the pots. Change tubes first, check for loose grounds then start looking for faulty components.
Are there any mods? So many times things are changed and the solder joints go bad over time. Even some of the work at their factory was not first rate. If modded put it back to stock and start over. You'll find out what's wrong somewhere down the line, those are not complex amps. Just go slow and do a little at a time and don't work when you're not 100%. I find that when I used to do that it's when I made the most mistakes. You cannot do this kind of work when you're in pain or discomfort, you need 100% concentration.
Feel good, take care of yourself and don't let anything get to you, it's not worth it. People ask me why I look under 40 when I'm over 50, I just say I stopped giving a crap about the little BS things in life. If I have no control over something I can't control it and that's the end of it. I always do the right thing but that doesn't seem to matter, I can't control the world around me, I can only control me.
I think if I still smoked I would have been dead by now. Good luck!!!
