Is the resting plate current normal?  If so, the zener is not your problem.  
What is the SWR looking into the amp?  Is that low?  Is your exciter folding 
back in power?  Is the testing being done in a dummy load?  Have you tried 
changing the coax between the exciter and the amp?  Perhaps your antenna is 
suspect?  A dummy load is the only proper way to test an amp.  What say to these 
questions, then we can proceed from there.  73 Louie King Conversions
