I have a Mark IIC+ 60 watt that was last over hauled at the Mesa Factory in 91. I have done little to it since then except change the tubes. It does not get a lot of use sits mostly I gig with my Twin but if I am playing an exceptional large venue I run them both through an AB and run the Boogie clean and use the lead channel for that extra kick. This config seems to deliver a pretty cool sound.
Anyway I set it up for this config last week and found that all the controls except the treble are super scratchy. The most offensive are the Volume 1,Master, and Middle. Do you think my preamp tubes are crapping out or do you think the pots need to be cleaned, resistors replaced, bad caps? I love this amp but it is unusable like this.
Any ideas.
Mark IIC+ SR #13838 with the EQ.
Thanks
