I am storing my uncle's spec 1 and spec 2 components. I decided to hook up the spec 1 since he said something was wrong with it. I wanted to see what it sounded like. The left channel works pretty good, but the right channel barely plays and fades out if you mess with the bass, treble or volume. I used it as a pre-amp only hooked to my yamaha mx-800/u. The volume, pots and switches need cleaning. The spec 2 supposedly works fine, haven't hooked it up yet. Anyone have a guess what might be going on with the right channel of the spec 1? Thanks in advance.
