Boy ! your timing is perfect. I had been doing little mods, winding a
toroid, checking waverforms - and I moved the DDS synthesizer box about six
inches at that time. I must have  touched the knob - and noticed a while
later - and reset the frequency.

Thanks for the continuing report. New toroid installed as rf ammeter ( sorry
- milliameter ) and checking some of the numbers.
Because I am not using balanced NPN - PNP pairs I am not getting a
symmetrical waveform. Output - across a 50 ohm resistive load is not
symmetrical above / below zero. Adjusting the balance control on the gates
not adequate to clear the problem.
One transistor has nominal B=90 and the other B=200 .
Efficency appears to be very low also --- approximately 55%.
I will leave for the moment, as all is very cool, and will be even cooler
after I move the amplifier out to the coil. I do plan to change the
transistors shortly.

Thanks again.
