Combination Cassette Tape Head

Hi and seasonal greetings from New Zealand.

Does anyone know a supplier of replacement combination cassette heads? I have been working on a Toshiba PC-X88AD, had transport issues and required a new Aurex chip but got it working fine and nicley aligned. Been sitting on the shelf for a couple of weeks now there is no replay on the right channel. Measured on the head the RH replay has no continuity.

Thanks.
