I built the amp about 18 months ago.
Now this amp has over 300 shows to it's credit and my main giging amp.
It was used on a Major Australian musical for 8 shows a week for 3 months.
Tonight power up----> main power fuse is blown????another fuse same. no valves same..... Had to use another amp for the show.
Just got home from the show, had a look does not smell good. I'll check but I'm tired and not willing to go further after a show.
Anyone experience problems with the PT?
I know not many other users will have put that much mileage on an amp.
But my 1964 Fender has never failed in this area (that is 45 years old).
