Quang Hao,

On filament PCB, there is resistor R1 = 500 Ohm in parallel with the trimpot.
The total impedance (R1 // trimpot) can never exceed 500 Ohm, is this resistor R1 additional/intensional?
I can not find R1 on the schematic.

Quang Hao,
When each PCB contain 2 Simpler Simplistic, we will have to change quantities.

I spoke with Jean-Charles, we leave near by, and we meet often. I'll get with him and we will buy 4 PCB total, and share the shipping cost. Hence I updated Jean-Charles quantity to 4 PCB.

Compliments for all the nice work.
A question out of curiosity: why is the layout of the second HV-shunt in opposite compared to the other?
Depending on the mounting in the case this might be convenient, or not.
The two layouts of the heater-reg are the same.

Arjen.

I'd love to have room for heat-sinks for IRF840 and IRF9610 on the HV PCB.
