All new caps, except for the ceramic and mica, the electrolytic & paper have been replaced.
Did a quick check of the power resistors, in-circuit, but not out.
There seems to be a ton of info on how to clean tube pins , but not so clear on how to clean sockets safely.

Going to polish the pins till shiny, using cleaner, buffer.
Some say to use pipe cleaners on sockets, but I doubt there is one small enough for the 7-8 pin minis.
Some say just spray socket with cleaner (deoxit) and stick the tube in and out a few times.
