Built around 1961 this $10 purchase held a little surprise - a reverb unit! As in play-that-guitar-with-some-vibrato reverb unit! The reverb spring unit itself has Hammond organ branding on it, and a control unit using an EF80 and a pair of 12AX7s is connected.
I have NO idea how this works. Any clues from the guitar guys?

Hi aardvarkash10, even if it come three years too late:
A friend of mine just take a Philips reverb stereo console, for a similar amount of money you paid. The unit got a lever (!?!) control for the reverb, It's probably older than yours, speakers are frontal, side, an down firing, for a total of seven drivers.
Sadly it's a transformerless circuit, and the speakers are most probably 800 ohm units, I'll check this, next week end. Output tubes are UL84 40volt/100mA filaments.
I'm posting you the circuit, just in case the reverb unit have some similarities with the one you got.
