Studio pre problem

[BobMac]

I got a Studio pre about three weeks back. Two nights ago at practice one of the out puts stopped working. I turned it on again yesterday to see if i could figure out the problem. for around twenty mins it was perfect then the volume dropped on the same output. i took off the top and switched around V4 and V3 but same problem. the signal seems to be coming in and out. Very much like when you have a bad lead and your shaking it around to try and fix it. all my leads are working fine tho.

Any ideas Fellas????? New valves maybe(hopfully) ??

How about a dirty jack? Copper bore brushes for pistols work great to clean the contacts.
