Allow for at least 300ma for the heater, and at least 10 ma for the plate voltage.

Cheers,

Kris

Hi Kris
I will use two transformers like on Jakobs schematics. One 220V to 12V and one in wrong way 12V to 220V. It means that 300mA plus some curent is enought for both. What enought?.

You will have to experiment with the ´transformers, as transformers behave differently.

If you use two 220:12V/500mA transformers, it should work.
