The schem is not very clear, btw
At conector #5 in the 'head' I don't get +120 volts
At conector #1 in the 'head' I don't get +59 volts (I get more or less, 7 volts.

The power supply works.
The mic works. All the voltage measurements are correct except on those points mentioned above.
???

Any help, please?
Thank you.
