Have owned this amp for more than 15 yrs. but hasnot been inline for at least 10 yrs, lost interest but resently got the amp out opened the case and cleaned out the dust from sitting on the bench. Decided to just turn the power on and let the filiments warm up for a while. Plugged it up and made sure nothing was on turned the power switch on saw that the meter lite glowed for a second and was a hum from the transformer and the fuse (15 amp) blew. The one on the transformer did not blow also a 15 amp. Have looked it over and only thing I can see is the big caps on the bottom look as if they have leaked. Know that this is an old amp and that caps don't last forever. Question is (is this a good place to start or am I overlooking anything?) Thanks Also took some pictures and could post them.
