I have an amp I built a few years ago. 10 - 160m YC156 The tube has high
capacitance
and operating on 10 and 15m results in higher plate current at reduced output
(600 watts). I
knew this going in and was curious if the problem can be solved. I am using a
pi tank circuit.
Plate v = 5300vdc
I have heard (but not tried) an inductor between the plate and blocking cap
will help. Probably around
.6 uh.
If I recall correctly the total capacitance of the mounted tube and tuning cap
was around 65pf
Anyone have experience or comments on this application?
TIA for any comments
