NTE236 or 2SC1969 is only rated to VCEO 25V, seems low and no room for poor SWR? But datasheet says "...ability to withstand infinite VSWR when operated at 16V, Po=20W, f=27MHz."
The stock
Sanyo 2SC2078E 2SC2092 is 75V 3A 45-60pF, hFE 100-200, fT 150MHz, crosses to
NTE235 but hFE range is 25-200; and it's around $10+shipping. Eleflow 2SC2078 is 35V.
I thought if I have to mess around with tuning the output capacitance and base drive on a substitute part, why not change to a $1 IRF510 or IRF520 and at 100V it might be a bit stronger for poor SWR.
No end of terrible CB hacks out there to get more than the legal 4W AM. I didn't realize until I saw the bonehead youtube videos
Not my intent, I'll try changing to the IRF's as a learning experience. I wish I could check IMD or access a radio test set.
Just waiting to get the receive section working, and for
$3.00 50R 250W dummy load resistor to arrive and assemble a heatsink, current transformer, as my old #47 lamp is not the best
