Re: FM tuning drift - any ideas?
Thanks again everyone for your help, I have the circuit diagram now so I feel more confident in delving inside the front-end box. I think I will try a "new" ECC85 first and then have a close look at the HT feed resistors, along with their ascociated decoupling capacitors. Failing that it's back to the Beomaster 900K, all transisitor and with AFC...
