Illuminati (2nd Degree)

Hey-Hey!!!,
I have a bit of stuff distracting me right now. I plan to put the mono amps on a 10" x 18" plate. I need to make a drawing of the layout, and I'll publish that as soon as it's done. Going to leave room for grid chokes, but build the first with grid resistors for cost simiplicity reasons.

The most critical thing left to set its value for is the dropping R for the front end g2, and the size of the capacitor for bypass to ground. Since it's a PP stage, the bypass cap size is a bit less critical.

Got some cool frame-grid, high-gm pentodes for $2 each at Radio Electric Supply...looking good from here.
cheers,
Douglas
