Does anyone know what the internal circuitry was?
That’s one of Avantek’s “low cost” hybrid MIC amplifiers. I used its
brother GPD-464 a fair amount back in the 80s. They were cheaper than their
very nice GPD-211 iirc.
AFAICT it’s a vanilla NPN Darlington, like most others of that era.
I still have the databook someplace, I think.
I think you mean MMIC
Danke,
Nope.
It’s a hybrid, not monolithic.
