Default Schematic for heater power supply

Hi Quanghao,

Do you still have the schematic for the heater power supply boards that used to come with your sshv regulator?

Kind regards,
Bas

Sorry Quanghao

It was for the one resistor you put in place of a potmeter. But I've found out the reason so no need for the schematic anymore. Sorry to bother.

Thanks.
Bas

I was also curious about the 470uF cap. But I just assume this is for the extra smoothing?
