Eric Barbour 6bm8/ecl82 reverb driver

I'm looking for schematic examples of ECL type tubes used in a reverb driver circuit. I read that Barbour had a reverb mod were he replaced the 12at7 with a 6bm8 but can't find the schematic on the net.

So if anyone has any schematic examples of this application I would be most obliged.

I believe the real Barbour circuit is carefully guarded, but this seems to be the basis; it's from Svetlana and may have even been an early Barbour design, not sure:

Doesn't Victoria use a 6BM8 in one of their Gibson-derived amps? I dunno much about it, but I thought I'd throw that out there...

Hey, stumbled across this the other day, and thought I'd pass it along, seems like an interesting circuit to check out.

Sorry, no schematic as of yet...

(2 12 ax7 and 2 ecl82/6bm8, and one 6x4, I believe.)

don't know if that is useful or not, but I thought I'd post it....
