2203 (1979) bias caps

I'm replacing the bias caps in a '79 2203 as they have been pig tailed to the old leads and it looks funky.

If you've done this before did you lift the board pot side or valve base side?
I'm looking to disrupt as little as possible and avoid any unnecessary un-soldering /re-soldering.

How did it go for you?

Cheers.

I personally have not done it to that model but I believe someone explained a simple process awhile back. I believe they took all of the nuts from the pots and input jacks, removed them from the chassis holes and then flipped the whole board up and over enough to work. This way you don't need to unsolder any wires.

All done.
Was a bit tight but got there without disturbing existing solder joints on other components.
