Anyone know Cathode/Plate values of Grail tone Bluesmaster?

Post by Guitarman18 »

I'm about to embark on a 100W 6L6 BM HRM build. Having looked at the available schematics, I see that they each have different values for cathodes and plates. Is there any definitive info available from anyone who may have taken readings directly from a 'choice specimen'?

All info would be very much appreciated.

Cheers, Paul.

I don't know how definitive they are but 150k/120k on V1 and 220k/150k on V2 seems pretty nice to me. I've tried them all and the clean channel was quite a bit nicer to me with these, and I could dial the OD channel great as well. Cathode resistors were 3.3k, 2.2k, 1.8k. You might like a different setup though so swap things around.
