Hi again:
I initially intended to ask if about 1A of input current will be enough
to really get reasonable power output?
This comes from a simple calc from Pout of the TRX, which is about 100W
producing about 1.4 A of current into 50 Ohms.
Also, for this tube, what type of input circuit would you recommend when
trying to cover all bands up to 30MHz ?
Thx again for all info.
