I am such an idiot. My beloved 700 RB (the only amp I've ever purchased that wasn't used) has bit the dust by my own doing. It has always made a popping sound when I power it up. It always bothered me a little but I thought it was normal because it did it since the day I bought it 7 years ago. I read that if it was bad enough to move the drivers a little on my cab then I should get it fixed. It is long out of warranty but I contacted GK and found out that replacing two transistors Q11 and Q14 would solve the issue for good so I ordered them. They were super helpful and recommended taking it to a GK authorized service tech but the closest one is 2 and a half hours away and he estimated that it would cost $200. I have a fair amount of experience with a soldering iron and I can read a schematic so I decided to do it myself. Bad idea...Long story short I got the iron too hot and a little dab of solder melted into the board when I tried to get it off the printed circuit peeled up. I am sick to my stomach. Now I either have a parts chassis or I need to buy the main board used. Ugh!
