Bugera Trirec Infinium

[J M Fahey]

Just love of History.

Which to boot has the disconcerning trait of repeating itself over and over and over and over and .... well, you guess what I mean.

I've been to Prague few weeks ago But back to the amp, Bugera refuses to give anything out :/

Consider finding a different technician.

Several possibilities come to my mind, and I am sure to the minds of others. An open grid return resistor or connection on a preamp tube.

I already found another tech to whom i'll bring the amp on monday. He said that it shouldn't be a problem without schematics.

I foresee a Third Defenestration.

This kind of event requires musical accompaniment! Evvabody sing along now. Here's the chorus:

"Then... I....
Threw it out the window
threw it out the window
threw it out the window
and that's all right with me!"

Might try replacing the channel switching pedal, they have incredibly flimsy little pad type switches in them. Sorry just saw the dates on this old post.

I've had the same issue with the Trirec Infinium, ch.2 and 3 very low volume. I fixed it with no schematic, as I recall it had no 100K cathode resistor on the tonestack driver. That's the 3rd 12ax7 counting from the input. This stage is only active on ch.2 and 3.
