Ciao,
come li hai riconosciuti che erano proprio quei due condensatori? A vista sembravano sani. Avevano perduto acido?
@Fabio
Ciao, un condensatore elettrolitico non deve perdere per forza acido , bisogna testare inanzitutto i condensatori con questi strumenti:

Giusto, l’Esr che deve essere basso. Generalmente che valori sono tollerabili per considerare un condensatore ancora buono?

Hello,
I’ve recently come into possession of a used TCM-848, and I’m having some trouble with it. I have plenty of practically-new tapes, which are just fine and well taken care of, but I believe there are problems with the speakers in the cassette player.
I’m not very knowledgeable in these sort of things, mechanical repairs I mean, and I was hoping you could help me?
All the buttons work just fine, but when I press “play” the player only makes a soft buzzing/humming noise, though I can also hear the player turning the tape.
What should I do to fix this?

Hi Michelle,
Unfortunately there are too many variables for a remote repair, better if you find a good repairman in your area.
