Vintage SVT Stopped Working
Just got my vintage '72 Blueline SVT restored and she was working when I tested it at home. Yesterday when I went to go recording it wouldn't work so I had to use my backup amp.
I'm going to call the engineer who worked on it for me but thought I would try you guys first for advice as the engineer is a long drive away.
Basically it powers on fine and everything but I can't get any sound out of it. My speaker cab is responding by making a hiss when its connected but I still get no sound. I have tried both channels on the amp.
I must admit I am a bit confused about the impedance issues with this amp and speakers. Its an old amp with no instructions on the back like the new ones. So I'm thinking maybe I have connected it wrong or something?
I have an Ampeg 810E, 610HLF, 410HLF and 410HE. When I tested it initially I tried it on the 810E and it worked. I cant remember exactly how I hooked it up as it was confusing but it worked nonetheless.
The engineer said its a 4ohm amp from memory. The SPEAKER out is 4 ohms and EXT SPEAKER out is 2 ohms. Any help appreciated.
