Jim,


  Is it biased class "C" for CW usage on 6 meters?  If so it should do a
bit better that 65% efficiency.

>> No, Amp is for SSB use only, No CW<<

   What condition are the 3-500Z's?

>>Tubes are new from RF Parts, I know that doesn't mean they are good, I'll 
>>have to try them in my other L4B.<<

   If the Drake L4B is rated 1,000 Watts on CW I would not expect 1,000
Watts on 6 meters.

>>In original form in SSB mode it was rated at 2000 watts PEP input with 100 
>>watts of drive.<<
