Again in presumably the early Nineteen Sixties, [David]’s grandfather purchased a console stereo that includes a document participant, AM/FM radio and a slightly astounding stereo speaker system that might be greater than sufficient to cowl a small live performance corridor. Having inherited this piece of auditory artwork after his grandfather’s passing, [David] has given the console stereo a outstanding place in his front room, which is the place we begin the tour in a brand new video on the [Usagi Electric] YouTube channel.
Being a Fifties-vintage design that acquired produced into the Nineteen Sixties in a wide range of fashions, the Magnavox Live performance Grand is an all-tube affair, with the one presence of semiconductors being the three transistors discovered within the ‘Phantom’ distant management. [David] sadly doesn’t posses this distant management, though the receiver module is current within the unit. It seems to be just like the 1960 1ST800F in possession by [electra225] over on the Basic HiFi Care discussion board, which might present 50 Watt per channel, but as famous within the discussion board publish, the 44 tubes alone draw about 250 Watt, with [electra225] recording 377 Watt whole with every part cranked up. Clearly a excessive energy invoice was a value one needed to pay for having high-end audio again in that period.
After [David] takes his unit aside – made very simple because of the modular building – he goes by the essential circuitry of the facility provide, the amplifiers and even has a peek on the circuitry of the distant management which seems to make use of primary frequency modulation to switch the supposed motion to the receiver. All of that is made fairly simple as full schematics can be found for your entire system, as was commonplace again in these days. Attention-grabbing can also be the I/O module, which options an MPX part, for demodulating stereo FM which wasn’t standardized but on the time. Lastly, tape drive connectors can be found, which might have been seemingly a reel-to-reel unit for optimum HiFi enjoyment.
With the one damaged factor in [David]’s unit being the snapped wire on the tuner of the radio module (paradoxically brought on by the disassembly), all that was modified earlier than reassembly was a great clear, after which the console stereo was put again and examined. Reflecting an period when HiFi gear was alleged to mix in with different furnishings, it can seemingly proceed to do service for [David] because the world’s fanciest TV soundbar for the foreseeable future.
