While cleaning out the garage today, I came across the high power 400 ohm Ohmite rheostat Gates used in their 1000 watt-class plate-modulated AM rigs for the adjustment of the high voltage to the RF final amplifier and class B modulator stages.
It's yours for $25.00 plus the cost of shipment via FEDEX Ground Service.
You can PM me at
triodes@optonline.net if you are interested.
Thanks & 73,
