Anybody try 6L6 tubes in their CCV yet? Not sure if there's enough bias range in the supply without changing bias resistor. I know Mark had CCV shipped at one point with them in it.
Those Golub's rip, especially done on a JMP as opposed to the 90's S/L's. If you want a kick ass Aldrich mod from Mark, I got one more here from the 90's done on a late 70's JMP. It romps too, like the Golub, but with depth and resonance control on the rear panel. My OCCV can cover the tone, so it is aging like fine wine.
