new preamp?

[Ianm2]

I have just had a thought, never seen a pp preamp like this...

any ideas, would it work, say with a 6922 as the output?

WEll a very brief bit of modelling seems to work, 7ma bias roughly, 15k plate-plate, 600ohm output, 150 volt b+, 390 ohm cathode resistors....looking ok!!

Use 150volt supply for the first 6922, 10k ohm resistors, 100k grids, 0.1uf caps, away you go. push pull preamp, its a must try...

cancel that, the phase inverter needs attention!!

bugger, the output stage has already been done by none other than lynn olsen....ah well, and that goes back to western electric, interesting I came to the same conclusion as olsen tho'...wihtout prior knowledge...

I know everything I stumble into is 70 years old, what a bummer.
Dont give up, keep active.
