[HomeBrew] dentron GL-1000 no grid output

Sat, 2 Feb 2002 10:09:29 -0500

  If you don't have any plate current at idle or with
drive I would check into the cathode DC path back
to the B-. Also make sure you don't have an open
plate choke. Make sure the grids are grounded for
DC and RF. If all that checks I'd look at the tubes.
