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
