I mean on a PCB its very easy. I realize the in the RF section it "may" cause some issues depending on if its in a tuned circuit, but all the coupling an bypass caps, all the plate/screen/cathode resistors etc...

At least you would know its all at the base line values.

just thinking out loud. guess its a form of "restoration vs repairing".

I realize that shotgunning paper caps is the norm, but I was thinking shotgunning everything in sight that is readilly availble. Not that I plan to do it as it seems like a lot of effort, just wondering if anyone else has thought along these lines.

mine have been done that way, but it takes a huge amount of time, a bit of cash and it leaves little to mess with, but still does not guarantee perfection such as my ctc9 still goes out of wack intermittently and a real pain to find now that its all new in there.
