It works!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The reason:  I thought the Antenna Inductance needed to be near zero, and
it really needs to be at 40 on my set.   I'm getting about 25W out with 550
Ep.

I'm using a 100 pf 5KV RF capacitor (from some discarded SB-200) at the
antenna post going through a test clip to the center conductor of my coax
(which obviously needs to be improved upon....... and I think I need more
than 100 pf, but it's on hand.....).

Next step is to put a milliamp meter in the B+ line and try my RF Ammeter
and take some more measurements.

I'm a happy camper!   Thank you all for your helpful comments!!!   I will
keep you posted!
