Dynaco initially had preamps called the PAM-1 (I'm guessing Pre Amp Mono version 1) which used the sockets on the front to pass the signal (instead of the RCAs) and for power.  After the invention of the PAS2 (Pre Amp Stereo version 2?) you would use the RCAs and that was pretty much that.

You also use the octal sockets on the front to measure the bias voltage and keep it in check.

Pre-Amplifier Module One,  if my aged memory cells can be trusted...

Used a selenium-stack rectifier  (pffft!)

A pair gave true dual-volume control stereo, without that balance-control bleed that was debated heatedly.

Yep, that's the one... the selenium rectifiers are easily replaced with a 6 cent diode these days.

Heres a nice kit if your on a budget and have some basic soldering skills and want to play with tubes for under $200......not as much bling as the Mini-Watt, but it is 8 watts per channel
