Ken, I am presently restoring a Western Electric 250 watt transmitter, designated 451A-1. Have you ever seen one of these units. I assume that they are rather rare. This was a back up transmitter for a local radio station and was first placed in operation in 1947.
I would think that anything made by Western Electric would be a collector's item. The tubes in this unit, particularly the 350B audio tubes bring big bucks. Thank you.
