The only problem now is one that I've been plagued with only on some of my old 70 yr. old P.A. rebuilds, which is i had always been correctly advised was DC Grid Leakage,,, yà know, that ugly noise that accompanies the movement of the guitar’s volume pot, a variable resistor. Pots are good, tubes are good, & the same guitar will NOT have same affect on ANY of my other amps. My local tech, who's more of an all around electronics guy, but not a musician, did his usual stuff... Even after going back to him a 2nd time for the same issue, he couldn't kill the issue,,, and I'm really bummed.
In the photo, to the far left you can see the little cluster of a chicklet cap & a resistor. Before departing his shack, he gave me a .01 cap to put from my guitar's switch to the volume lug in the guitar in hopes of fixing the noise which typically happens between 8 & 10 on said volume pot. But what about my 20 other guitars?? This ain't right,, and annoying as all hell....
What to do now, folks? I don't touch this stuff, but my tech can easily follow any likely recommendations. FYI, those are the preamp tubes above his handywork...
a 6AV6 & a 12AX7.... Elsewhere, there's 2 6V6's & a 5Y3.
And, Mark, if yèr out there, please, chime in....
Thanks in advance & something's gotta work, Kenny ॐ
