El 84 Oscillator puzzle

The erase-head voltage is really low at 3Vpp, that's almost like a short-circuit. The original erase-head might be a different part? or the 0.022uF capacitor in parallel I would experiment with. Try go up and down in value and see what happens, you can add series or parallel capacitor to change by say +/-20%. It's OK if the oscillator moves to say 60kHz.

But the oscillator has so many capacitors, five that would affect tuning.
The main ones I think are the two 0.0022uF 100V parts (at the plate) which are too low voltage, they should be good to 400V and the value might be wrong there. Is it two series 0.0022uF to give 0.0011uF (1,100pF)?
I saw another Meazzi use a trimmer capacitor, guessing it is the 220pF/150pF to set amplitude to the record head.
