Polarity of cassette player

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?
thanks,
Kate Lucchese

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

My unused WM-FX 195 doesn't play cassette


Fault with the drive belts, remove rear covers and take sample belt to buy and replace. Might be difficult to get them but in old stocks.

I have a Nakamichi BX-300 cassette deck. The idler wheel assembly is broken. Where would I be able to find a spare?


Definitely the spare will be available with the nearest Nakamichi dealer close to you as you will need to check on your yellow pages or the net. But if there is no hope thenthe best way to go about is to identify the repair shop closer to you that has old sets, Youmay be lucky to find and salvage from an old set which would have the mechanism intact but with an electronic failure. Please search also on the site here for the NakamichiBX-300 models which had a serious failure to be bartered. hope it works out. Good day.
