Unhappy Trace 1225v combo issue

Sign in to disble this ad
Hi everyone!!!

I bought used Trace Elliot 1225v combo few months ago. Never had any problems with it till yesterday. In the middle of the soundcheck suddenly all the sound was gone, and all that i have from the speakers is loud hum. I've turned off the amp, and tried to put it on after few minutes. Nothing happened, only hum, no other sound, and the clip indicators next to the preamp knob are flashing like they usually do when i play, but nothing coming out of the speakers except hum.

After an hour when i came back home i turned the amp on again and it worked, but only for 15 minutes, then started to humm again... After that i plugged the extra cab with 2X10 instead of a combo speakers, and same thing happened, so i definitely figured it's the amp issue because the other pair of speakers works fine with Peavey bass head i own.

Today, the same thing, turned the amp on, worked fine for 15-20 minutes, then again hum. Later i just turned the power on, didn't plug the bass or any cord in, and after a while same old hum. Both volume knobs are totally @ zero position and it still hums. Intensity of noise stay the same as i turning the volume on.

Anyway i'm planning to play it for a few New Years gigs, and thought of taking it to the service tech these days, if anybody have any suggestion or idea what is wrong with amp, or ever had a problem like that on other kind of gear, please write it here, because here in Serbia we don't have authorized Trace Elliot dealers or service, so i have to take it to the local „tube guru” and i suppose it will be much easier if i give him few options before he open it...

Thanks in advance!!! Cheers!!!
