Honestly, in my experience I've noticed that a real bird 43P reads more peak watts than a well-adjusted dosey. And if you really want to see a lot of peak watts buy a CDI peak reading meter.
Most of the dosy meters that I've seen in the last 10 years or so have been calibrated pretty stingily...
If you are discussing using relays for RF switching like in a tuner or an amplifier the switching speed is not really a concern as long as you stage them properly. On bigger boxes, 5kw+, build any kinda circuit you can muster to make the output relay close before the input relay so it never hot...
I feel like I saw this on another amplifier one time. I remember seeing a schematic where they used two chokes one to each side of the cathode and they were tied together and the b minus attached to that. Wouldn't that kind of be the same thing as a center tap on the transformer?
My advice
Get a real CB radio like a cobra 29 or 148. Any flavor, just go buy a new one. Not a 30 year old project.
Go buy an amplifier, don't worry too much about brand etc. Install it well, get a Wilson antenna, roof top or something to mount on a bed rail. Nothing too small. Tune it. Enjoy...
