Nisbeth,
I'm not sure which schematic it is, whether its MOSfet or BJT....
I only know it uses an unusual feedback scheme with the typical electrolytic to ground replaced with a series film cap (with a topological change).
The schematic was referenced in an aritcle in Audio Amateur 1996, issue 1. by Richard Guest, 'On Power Amplifier Feedback Networks". It uses the typical JLH Cdom 5pf from the Vas collecter to the feedback node, 150k & 1.2k resistors, and 9.4mmf cap.
So I actually know the confiuration and values of the feedback scheme, but I don't know the context in which it was implemented.
Thanks,
Paul

Thanks for your kind offer. Geoff just emailed me a scan of the circut.
Thanks again,
Paul
Hi Geoff,
Would it be possible for you to e-mail me the schematic too?
Thanks in advance,
