Hi,
I'm working on a Selmer Treble & Bass mkIII reverb head (50w) and its been mauled inside by someone previously. The amp has no headroom and distorts at almost any volume.
I've traced the schematic out and have a few ideas where things have gone wrong (pieced together from a few Selmer schematics of the period as I couldn't find an exact match). The 6BR8 reverb driver is a weird one, never seen this before (pentode/triode in one envelope).
Anyway, if anyone has some chassis-gut pictures of this same amp, I'd be grateful if you could post them on this thread. There is an entire stage prior to the reverb pentode that has been removed and it'll be quicker if I can get a photo of another amp's guts to work off to see how this amp originally was.
Thanks in advance for any help.
