After having my AL 811 in storage for about 10 years, while living overseas, I recently tried to fire it up. Made all of the right connections. Have the nominal 1700 volts. Keyed the exciter (no drive ). Transmit light went on (relay works) and the plate current is 110 ma (what it should be). Then I applied more drive to get the required 50 ma of grid current so I could then adjust the plate and load controls. Result was no grid current, and no responses to plate or load adjustments, and no power out. Would this be an indication that during the 10 year layoff period, my 811s have gone bad, or could it be some other problem? Years ago, when I operated the amp, I never had a problem. I am driving the amp with my IC-735, which operates great running barefoot. Help! Thanks. Dave, WA6TXU.
