[Hallicrafters] Varacs

[Mark K3MSB]

The HT-37 manual states that the transmitter requires 370 Watts, and
accepts a voltage of 105-125 VAC.

Assuming you use the variac at 115V, the required current rating of
the variac must be at least 370/115 = 3.2 Amps (P=IE).  I'd go a
little higher for transients.   Yes, you can you a variac for
transmit.

Price are all over the place.  Check the on-line autcions, qrz.com
etc.  Hamfests are typically a good place to find variacs.  For a 5A
Variac, you're probably looking at around $25.
