Restorasi JVC RC-M70W : Super Jadul Boombox Tape Recorder Radio

Repairing a JVC RC-M70W cassette player and radio, manufactured in the 1980s. The initial sound was intermittent, and the tone control potentiometer was damaged. The component was scarce, so we replaced it with a different potentiometer without disturbing the PCB circuitry, and the result was a full-fledged repair. The tape mechanism had problems with the pinch roller, tape head, and flywheel belt. The power amplifier uses an AN7145KH IC with a maximum power of 15 watts per channel, a 2-way 15-inch full-range speaker, and a 1.5-inch tweeter. Thank you to Mr. Yudi from Bekasi, West Java, for the equipment.
