First, disconnect the power. The voltage in this unit will KILL YOU!
Once a year, remove the case and covers. Be sure the HV shorting strap/bar
is in tact and does short the HV supply. This is when the unit is being
serviced and out of the case.
Clean the fan blades, add one drop of 3 IN 1 oil to the shaft bearings.
Take care not to bend any of the fan blades. Clean any dust from inside
the case using one of the "computer type" compressed dusters. Look for any
discolored connections, discolored areas on the PC boards and, specially at
the base of the tube sockets. If any exists, replacement or repair is
Put everything back in place and do install ALL of the screws. The amp is
ready for another year of working DX.
Proper tuning and loading and proper drive is the key to success for long
amp and tube life.
