Amp experts, some advice please!
I recently got my old amp out of storage, and something is a little wrong with it.
It is an SWR Workingman's 12 100watt from early 1990s, I'm guessing probably 1994-ish.
When I turn it on, there is a substantial pop. I will also get a pop if I fiddle with the cable end plugged into the bass.
Mind you, volumes are low - definitely within the first quarter turn for both main volume and gain.
When I was practicing yesterday, I had some popping because of the cable being fiddled because I changed the way I was sitting. The sound then became distorted, almost as if I had put it through an effect pedal, and then slowly died out.
But! If I fiddle with the cable some more, a pop or two later, the bass can be heard again. Although I don't think quite as loudly.
I have yet to experiment changing the amp settings from active to passive/active and trying with the back switch on "horn off."
This was(is!) a good amp and I would love to be able to salvage it. I wonder if it could be as simple as changing the fuse (or the cord?!), or if it is something more dastardly that requires professional intervention, or even worse, retirement.
As you can probably tell, I am clueless when it comes to electronics and wiring, etc. Any and all hints, tips and advice will be very much appreciated!
