Within the past 8 months I had my JCM 900 heavely serviced. New Power Tubes JJ Tesla 6l6, New Pre amps, Groove Tube Gold 12ax7 in V1 and V2 and Groove Tube gold 12au7 in V3
Also had the filter caps replaced with JJ Tesla 50/50 500v
I also had all the pots cleaned, and a few items in the pre-amp replaced. a few resisters and caps
The amp is degrading in sound quality. It’s not warm or full sounding. It’s not very loud. It has no top or bottom.
I would say it is as loud on 10 when run through a 4x12 as my 15 watt Vox AC15 running through it’s 1x12 speaker.
Any thoughts?
