[ARC5] Operation of ARC-5 Transmitter

[AKLDGUY .]

It is vitally important that the final tube screens NOT be supplied
with power while you check the oscillator. They will be damaged
if this happens. Your transmitter may have been modified, so that
they are connected to the oscillator plate supply.

If you are not truly familiar with how to prevent the screens being
inadvertently powered up, the best option by far is simply to pull
both 1625s from their sockets.
