Greetings gurus,
I'm a little bit lost....
I'm unsure as to the correct mathematics and methods
to calculate the input impedance and drive
requirements of an amplifier stage. Seems that I need
this info in order to design the inputs.
The project at hand is a 4x813 HF amp, cathode-driven,
with bypassed screen and bias supplies.
Hoping this isn't a ridiculously stupid question :-)
Many thanks in advance for any assistance!
Kind Regards
(KD5IZI/AE)
