RE: Scott 130 preamp question

I have a 1960 Scott 299, and I replaced the Pyramid Imp capacitors that couple to the output tubes to prevent major meltdowns. I didn't replace them in the preamp section because they weren't leaky and, IMO, sound pretty good. That said, I check them periodically.

Deoxit D5 works for RCA jacks, but if they are heavily oxidized, I may first use something a little more aggressive like Noxon 7 polish, which is then flushed off with Deoxit or CRC QD, a non-residue cleaner.

For the rotary selector wafer switches inside, these usually have silver alloy contacts, so I've used Deoxit D100 concentrate or some kind of silver polish. The black silver sulfide can be hard to get off, but it makes a sonic difference.
