Peavey ValveKing 100 Overhaul

[physics]

Brief update: Installed some new Kemet filter caps. Measured in-circuit capacitance and the (albeit inaccurate) value is much closer to what I'd expect. Mostly, I wanted to make sure I saw a change more than I wanted a specific value. I also removed that capacitor I mentioned going into stage 3, changed stage 1 and 2's plate resistors to 100k 1W each down from 150k 1/4W, and bridged the lead tonestack's mid pot leads so it's wired as a rheostat now. I also lifted a few more pads, yippee. I can hold the board up to the light and look through it at the traces on the opposite side, and I can see spots I've reworked delaminating. In most cases not even from what I'd call abuse either. It seems that dwell times need to be extra short on this board, and even then it's not guaranteed pads won't lift. Every time it happens I think more and more about making my own eyelet card.
