Perform a complete voltage reading
verification by comparing the voltages
stated in the schematic diagram. Please
allow margin of 10% on the reading, due to
the fluctuations of the main AC supply and
the electronic components.
Pay particular attention to the B+ and
heater voltages.
When checking the heater voltages,
please remember that the voltages have
been raised to around 90V above ground.
If you leave one probe on the chassis and
the other probe on the heater terminals,
you will be getting readings of around
90VDC and 102.6 VDC.
If you probe the two heater terminals, then
you will be getting around 12.6VDC (Again,
please remember that these are really high
DC voltages).
