Question about Audio Players & Recorders
Hi! We're trying to identify the polarity of an old GE 3-5025A cassette player so that we can properly install a replacement universal power adapter and not destroy the cassette player.
Do you know this model's polarity?
If your battery polarity was reversed then there is a possibility that a protection zener diode onthe set could be short as a prevention. so you will have to check on the + line input to the set. If not the amplifier could have shorted depending on the applied power. Anyway you will need a good check onthe main board to confirm this but I think with a tech help, it will not be difficult. Hope I could help. Good day
