John, do you have the amp plugged into the wall direct or, are you going through a power strip with a two prong plug? Sounds like you may have something close to your amp causing the interference.

Probably filter caps... after 35 years, time to see a tech!

If you turn the reverb to zero, does the hum stop?

Its not a hard job, i have done electronic repair for about 20 years. If you do it yourself just get good quality caps, id recommend Nichicon brand. i have used them in PA eq and high power HF stuff as well, they are highly recommended and only cost a fraction more.
