Thank you. I had suspected as much but my confidence repairing this piece is almost nil. It has tremendous sentimental value. A question on the earspeakers. As I rarely used them, and they weren't energized much, how would effect the condition of the diaphragm? They've spent the majority of their life in a bag in a drawer. I'd never had cause to use headphones, until recently.

I have a SRA-12S. I used it for years and one day, the dreaded 60hz hum. I have an electronics background and as a hobby I work on tube equipment, but I am reluctant to work on this myself. It's a pretty special piece to me. Is this something that any competent professional tech can fix, or should I send it to a particular repair place? Not sure on the condition of the headphones. They look great but I haven't listened to them in 20 years.
