The bypass capacitor at the base of the plate choke is to keep RF out of the
power supply and your house wiring. RF is very detrimental to electrolytic
filter capacitors. 1000 pf is not enough to do the job on 160 meters;
8000-10,000 pf will do the job nicely. You will not see any noticeable
change in efficiency. What is the efficiency now?
