hi,
I have a Mesa Boogie Studio Preamp (first revision, with a 12AT7 tube driver instead of a 12AX7 for the rev2). It is a nice preamp except the fact that it is not a true two channel preamp but the major issue that I have with my preamp is that the reverb is very noisy!
When I turn the reverb pot, there is a buzz or hum that is coming and there is some small cracks when I play. So I think there is something wrong with it but I don't know what! Do you have an idea?
And the last owner remove the two jacks on the front (input + channel switching) so I have installed new jacks but do you have photos of the wiring of these two jacks to see how that are wired on the orignal preamp?
I'm also seeking for photos of the wiring of the rear input jack and photos of the reverb to see if the others wiring are the same as on my preamp.
PS: here a link for people who wants to mod their studio preamp. It's in french but with an online translator you will be able to understand what it is written or write me if you don't understand something!
