In exchange for a selenium rectifier 1N4007, you can adjust the Bias ??. I remember having to change the resistor values pin terminal 7's for a proper fit.
I kept the original PCI, I placed a new PCI with orange capacitors and metal film resistors.

I also put a diode between the pin's of the grinding valves for longer life.
