MananaMan Posted February 7, 2009 Share Posted February 7, 2009 (edited) OK, bit of a problem with my TE head. I originally bought this last year before heading out on tour as it was the only decent SS head in the local shop, and I needed a back-up for my Marshall VBA which had been playing up a bit. On tour, the VBA duly killed itself in a flash of blown fuses (internal, so I didn't want to risk opening it up) and I fired up the Trace... Lo and behold, it sounded great. Brilliant thought I, SS reliability and great tone. A few months ago though the Trace started to develop a problem where the output will drop to unusable levels - it just turns itself down, in a way. There's nothing wrong with the kettle lead, or the speaker lead, or the cab. The pre-amp works fine (plenty of level there), and the DI works - its only the power section that goes funny. After about half an hour of being quiet, the amp starts to turn itself up again. Weird! The last time this happened (this week) the green backlight started to fluctuate in output too - this leads me to believe that its a power supply problem, but as I say I've tried four or five different power sources and leads so I can't fault the actual supply. Anyone got any ideas as to what is wrong with my "drop it from a crane" reliable amp??? *edit* for spelling Edited February 7, 2009 by MananaMan Quote Link to comment Share on other sites More sharing options...
