Yes you should add bias. I added 11 diodes in the center tap of the
filament trany. So that would be about 7 volts.

I just finished me Drake power supply. I used a Drake transformer
and a doubler board with 8 caps. I have 2600 volts showing on the
high voltage meter. I have eliminated all the bias circuit in the
power supply that Drake used. At idle I show 200 mills of plate
current. My question is should I add a bias circuit? I purchased a
W4ZT board but wonder if I need it. Thanks and Happy Holidays to all.
