Default Re: Sounds Belle reel-to-reel heads

Tape heads have two coils which are normally connected in series. Sometimes this connection is external, as appears to be the case here.

A crystal cartridge gives several times the output level of a tape head so your replay amplifier may be low gain, equally the head may be faulty. If you have a multimeter check it for DC resistance, assuming there is a reading (out of circuit) the head is probably O.K.

Ideally you should demagnetise the head after passing DC through it but at this stage don`t worry.

I assume you don`t have a tape with a known recording on it to try.
