Hi,
I just got this amp. Acoustic and clean channels are OK, the OD 1 + 2 only about 1/4 volume of what the clean channel is.
I replaced the Preamp tube /valve. No difference. Any other ideas what it could be?

I have downloaded a schematic for the AVT275. I could email it to you or find the link where I got it. Thanks for looking into this with me.  |

Do you have an audio probe? That might help track down the problem.

No I don't. Is that something Radio Shack might have?

I dont know if they are sold anywhere. Its real easy to make and use one. www.diystompboxes.com/wiki/index.php?title=DebuggingThis link shows how to make one and gives a little info on how to use it. The info is geared toward stompboxes but the idea is still the same. |
