Default Re: The "Sussex" Homebrew Valve Tester.

Hi Vesa
You have a nice job done on the cabinet

I am progressing rather slowly with the Sussex.
I've done a little trial and error with the resistors and there values are working out at something like

5mA 100R
15mA 33R
30mA 16R
60mA 8R
120mA 4R
180mA 2.8R

It would have been easier if I just did the math's
I don't think a 1mA range is necessary. The above test were done with a low HT of just 15V as I haven't got that side of it working yet.
It will be sometime before I get mine finished.
