Hi guys,
Dad had an old amp sitting around he hadn't played in years. Its an Ampeg Gemini 1. He thinks its a 1966. It seems to have the original tubes and most likely original caps, etc...
I'm really enjoying it, but its got a terrible vibration or possible electrical component related distortion, with certain frequencies. I took the back off and found this spring just screwed inside the cabinet. What is that for? Its not wired to anything. I took it out, but the vibration continues. I haven't dived into the rest of the amp yet.
Any advice on common things to look out for with these amps? Services you recommend doing? Anyone have a link to an old factory service manual or anything like that?
Other than the vibration, I'm enjoying the amp's sound. Its certainly different from my tweed deluxe
