Question on new 100W MV build

Post by LP Freak » Sun Nov 15, 2009 10:17 pm

I've completed my 100W MV kit. On the initial start up, I'm getting -136V DC across the 5.6 grid resistors. The instructions say I should be around -50V DC. I plan to post pics but don't have time tonight. I was hoping someone might have and idea what was going on.

Double check your resistor values in the bias circuit.

Don't let that smoke out!

Yea, it figures. I forgot to solder one end of the 47K resistor. Now I've got -50.2V. Thats what I get for rushing at the end! Thanks alot.
