Case # 741123. 07/15/2025 Tube Fisher Allegro A-19 console. Low sound on both channels.
Interesting unit from Fisher. Turntable, tuner and amplifier in one cabinet.
After cleaning and testing found one low/ middle range speaker in right door is dead. Measure 8 ohms coil but produce 15% of sound only. One preamp vacuum tube 12ax7 glows purple color inside and shots down sound in both channels. Filter and power supply capacitors after 60 years still ok. 60 years ago people know what word QUALITY means. Fisher use 2 door hinges as a speaker output terminals for speaker wires. That is unbelievable . Speakers connected to door hinges and amp output connected to door hinges also. Door hinge is conductive wire for speaker . That is how they solve problem amp connection with speaker inside the door . Genius !!! I Love it !!!!! If you have extra speaker you can connect it to door hinges directly .
