Subject: [Amps] HL2K high input SWR on 21 MHz

Hi all,

I have a HL2K amplifier (pair of 3-500Z) for several years now (got it
second hand) and it always had a high input SWR on 21 MHz. I matched it
with my TS850 antenna tuner, so it was OK.

During last contest i had a problem on 40m (500pF/*2kV* in output tank
shorted). So i had to open the amplifier and while being there i wanted to
see what's wrong with this SWR.

  Different subject:  I would more expect a 20 kV capacitor rather than
a 2 kV capacitor. ???

                Every action results in unwanted side effects.
