Tube Amp Archive

So I cut the jumper behind the 250K pot ,the one that was supposed to allow the EQ to work on channels 2-3,and I really didnt notice any difference,but it ruined channel 1 clean.I normally use the amp on the clean channel with my Boss ME-33,and after the mod,it sounded all tinny,and squealish,thin ,...

So I downloaded the schematic to do the jumper mod. It is true ,the distortion on this amp is so dark and muddy on channels 2&3. The Bright button does not work on them at all. So,without my Boss effect , the distortion is good ,but not nasty! I am going to do the jumper mod first,but I think I real...

I had somehow lost the link to this page and just found it now,after all this time. I am super happy to report that after 3 visits(and almost as many weeks in there) to the Amp shop in WPB,Florida, the amp was fixed.

Yes, I live in Palm Beach ,Florida,there is a Mom & Pop store called "The Amp Shop" I am bringing it there on Tues. It sucks ,to have probs that are beyond my reach.

It does not have a rectifier tube as far as I know . it has 4 6L6's in the power section and 3 12AX7's ,and 1 12AT7 in the pre-amp section . I am assuming that the Fender power tubes ,are not the stock tubes from 89' .I should be able to afford to replace the tubes ,but I thought that would be to si...

So ,I had recently bought this Amp about 2 months ago for $200 from CL ,and I was so happy to have a Tube amp again after having sold my Marshalls ,and 3 kids later ,finally trying to get my head back together! It worked perfectly for 2 months ,then all the sudden , I noticed when I turned it on ,an...
