Farfisa F/AR Preamp and Reverb Schematic

He is the Farfisa F/AR Schematic. The F/AR was an independent preamp and real spring reverb unit that was used to power the Farfisa Compact Duo dual manual combo organ, and the Farfisa Transicord electronic accordion. Both of those instruments will not work without this piece, so it’s pretty nice to have one!
