Need help on Peavey VMP-2 PreAmp

[Ron Randall]

One channel works like it should. The other channel has almost no gain. When I turn the gain to max and remove the 20db pad, I get just a tiny signal.
Is there something I could/should do to save a trip to Peavey?

Tubes.

Obvious try---mark all the tubes on the good side, remove the tubes on the bad side and then replace the bad side with the good side tubes. See what happens.

[Ron Randall]

Thanks Bill.
I will try it and report back.

[Mike Brown]

Thanks for the help Bill. You read my mind.

Ron, after you swap tubes, feel free to call me toll free at 1-877-732-8391 and we will be glad to assist you further if the problem is other than a tube problem. <FONT SIZE=1 COLOR="#8e236b"><p align=CENTER>[This message was edited by Mike Brown on 10 August 2004 at 06:28 AM.]</p></FONT>

uhhh....duhhh

Thanks for the help Bill and Mike. Simple as it sounds, it was a bit imposing for this mechanic. I did look at the manual and determined which tubes went with which channel. Swapped the tubes. Found the problem. Working like new again.

Ain't this Forum great?

[Mike Brown]

We try.

Glad you got your pre-amp going! These are one of the real "sleeper" pres in studio land, lots of engineers buy every one they can find. I love mine, wish I had another!

Mark,
Yes, I love these things. I have picked up three over the last coupla years. Lurking and sniping on eBay. Found one at a studio closeout sale nearby.
Brad Sarno turned me on to them. Great for vocals, bass, electric piano, steel guitar. Heck, you know what I'm talking about.
