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.
