Ampeg SVT-2Pro Problem

BigMac5 · #1 01-31-2011, 02:57 AM

Was playing the amp and the amp made a pop sound, the stand-by light started flashing between green to red. According to the manual it's probably a bad power tube.

Is this something I can figure out by myself or should I take it to an amp tech?

Amp tech, unless you know how to bias power tubes properly.

What about the bias controls on the back of the amp?

Manual says:

Red comes on, then green - Tubes not properly matched

Both on all the time - Possible bad bias control or bad tubes

That's probably a safe choice, there could be something else wrong with the amp.
