I'm sorry, but what is it? I found one reference to Sonny Landreth's Dumble, but it's not clear.

So what's the story behind the schem.
Rev.Eng or copied from somewhere else, has it been built and tested?

Does anyone have a copy of this? I took a look at it earlier today while it was up and I remember a couple of interesting things (this is all from memory and could be wrong):

47K slope resistor with .022 caps for mid and bass and a 50K mid pot?

330pF bright cap - ceramic

Different values than usual for the power amp NFB loop. .1uF cap on presence circuit. 100K feedback resistor from the output xfmr, IIRC.

.022uF caps coupling PI to power tubes.

.01uF cap from V2A.

OD coupling caps were .001 on V2A and V2B.

Most caps were SBE 6PS, but one or two were 715.
