The high voltage present on the plate choke and air variable
capacitors attract dust and dirt out of the air stream.
particularly important that the high voltage areas at the bottom
of the of the plate choke and the insulator on the air variable
capacitors be dust free. These areas should be inspected every
few months if the amplifier is operated in a dusty environment.
Unplug the line cord, and wait at least 90 seconds until the
power supply capacitors discharge.
