[BC] Collins 20V Reactor

[RichardBJohnson at comcast.net]

In the meantime, you borrow a pole-peg from your local electrical company
and "install" in on the floor behind your transmitter. Hook it up with GTO-15
wire that you can get from any electrical supply shop. You use its secondary
in place of the modulation reactor. Modern pole-pegs have one side of
their primaries connected to the can so you need to set it on a sheet of plywood
and connect the can to the B+ side, with the HV insulator to the modulated side.

Remind oneself that the whole thing is at a lethal potential. This will
keep the transmitter on-the-air until a new reactor can be built.

At a radio station old enough to have a transmitter with a modulation
reactor, there are probably other things hanging around that will work
for a temporary reactor as well. A spare plate transformer comes
to mind.

For those who don't like scary lash ups, you can always obtain
the modulated B+ directly from one plate of the modulator stage. This
should give you 65 to 90 percent modulation capability with low
distortion. You leave the secondary of the modulation transformer
unconnected.
