Sorry, once again posting on the same subject. This time to say that I figured
out what my problem was. Of course I need to jumper pins 9 and 10, they are
controlled by the HW-101 to turn on. I love it when a problem turns out to be
something simple, just my oversight.
But now I have another question, my 12 volt filament voltage is rather high,
like 30 VAC. My 6 volt filament is high also, like 24 VAC. I want to promote
long tube life and I don't think that will help. What can I do about that?
The HV and both LVs are 818, 365, and 275 VDC respectively. They seem to be
quite close.
Thanks again for any help you can provide and I apoogize for all the bandwidth
I've been using.
