[Henry] Sick 2KD Classic

[n6iiu at mlode.com]

My 2KD is acting up. When I key it with the exciter I get no output. Turning the Load and Tune controls do not affect the meters. Depending on input power the plate and grid meters work fine. But no output. 
Thinking it could be the relays, I swapped them for each other. No effect. Measured 18 volts DC at the relay socket in the rear. Relays seem to key but can't tell if both are firing. According to the schematic the imput realy is working but not the output relay. 

Any suggestions?  Unit worked well up to now. New tubes etc. 
Oh, symptom before this was while talking, output would drop to zero and plate meter stuck at 400 ma. Turning off the amp reset everything. Thought it was a grid to filiment short so replaced tubes with known good ones. No luck. 

Tnx for any help.

p.s. give me a phone number and I will call you if that would work better.
