Garnet amp issues please help

Postby Tjonmcd on Mon Apr 22, 2013 5:05 am

I have a little 7 watt garnet ( Canadian company) I love it and it was working great for a while and then all of a sudden I tried to turn it on and something strange happened. It started fine for about a minute and then it started crackling and popping and making almost firework "pew pew" sounds. It does this everytime I turn it on. Does anyone know what this could be?

what model is it? i have Gar's book and it has most Garnet schematics. is it a tube amp? sounds like a simple single ended champ style amp. Gar made lots of those but under a stencil brand mostly.

You may have a filter cap or other component ruptured from current heat. Have you looked under the hood for burnt components ? Check for pooched out ends on those filter caps and I assume you've already looked at the tubes.

Before trying anything else, I would switch all tubes with known good ones, assuming you have spares (always a good idea).
