Default Re: Grundig TK20 and Truvox R82. Help Required Please.

What's still puzzling me is that OP says in his very first post that, together with the hum, the audio (presumably he means off the tape) is very low and barely audible. I don't see how an o/c head would give any output signal at all. He also says somewhere that the hum varies with the tape speed. Does he mean varies in frequency? If so, the hum must be recorded on the tape.

Apart from those curiousities, it has to be an o/c head if the resistance readings now being reported are correct.
