Re: Ferrograph 4A: Restoration advice needed
Anode to g1 short in the valve? otherwise you have a lot of oscillator power going on because the only power reaching R35 should be erase frequency AC via the secondary of the oscillator coil... or has the thermistor gone low?
This circuit should survive without the heads, otherwise removing the erase/bias link will do damage.
