My experience of my PET was you need to demagnetise and clean the heads of the cassette players frequently as some models (particularly the built in one on early PETs) had D.C. bias. Symptoms were unreliable reading and failure to verify. If you look around you can find mains demagnetisers for £15-20, the type that have permanent magnets built into tape cleaning cassettes I never found as effective.
Thank you for that. Yes I have two and both can be temperamental. I have a black one and a cream coloured one. The black one is like the one built into the early PETs and cream one came with my C64 - I’ll check the demagnetiser out
