Greetings, Bottleheads...

So, on my Paramour, I've now replaced:

The hum pot
The 1.2K 10W resistor
The 220uF cap

IOW, everything in the heater filter circuit.

I still get nonsense readings from A1 and A4 to signal ground. Starts at a low resistance, rises to infinity, drop instantly to low, rise to infinity, repeat forever. Think of a sawtooth wave.

I've got no idea where to look next. The only thing left in the circuit is the power transformer, and I really don't want it to be that. And if it is, it's the quietest, non-stinkin'-est transformer death I've ever seen. Usually they die very gory deaths.

Thanks,
--Shannon
