Quick answer, more later.

1) You can test the input with a potentiometer and voltmeter. Input lead is biased to B+ with one megohm, electrodes ground out successive resistors in a voltage divider inside the little black module by the tank. Result compared against similar network at the left-side LM324 chip.

2) The LM324 chips die a lot.

3) Some info and schematics here

Gotta go, back later.
