Well I accidently hit "SEND" before I was done, LOL.
The test transmitter for this is an original -AH with
the original tubes. 6AQ5s or 5763s will put-out more.
To use 5763s, you need to pad the Neutralizing capacitor
with about 3 pFd.
I have a 50 pFd "doorknob" capacitor in series with
the antenna feedline which lets the transmitter output
match the 50-Ohm feedline. Scope says max output
into the dummyload is 36 V P-T-P with equates to
about 3 Watts out.
