DYNACO VINTAGE STEREO EQUIPMENT AND I'M THE ORIGINAL OWNER. PAT-4 PRE AMPLIFIER, STEREO 120 POWER AMPLIFIER (60 WATTS PER CHANNEL) FM-3 TUNER. THE RIGHT CHANNEL ON THE PAT-4 PRE AMP HAS TO BE SET SLIGHTLY OFF CENTER TO THE RIGHT TO BALANCE BETWEEN LEFT AND RIGHT CHANNELS. THE FM-3 TUNER WORKS, BUT CAN DRIFT OFF FREQUENCY, an alignment would probably fix this. Also the FM3 has had the tuning eye tube modified since the original tube went extinct. The tuning eye tube bars come together for tuning, but the "Stereo" indicator does not work. Very good cosmetically. I HAVE ALL THE OWNERS MANUALS. I WOULD LIKE TO SELL ALL THREE PIECES TOGETHER, BUT I WILL SELL THEM SEPARATELY @ $80.00 EACH OR $200.00 or best offer FOR ALL THREE.I will except PayPal cash payment. *** NOTE THE GROUP IS SOLD AS IS! ***
