Stan and I visited the site yesterday.   The old 407, Western  Electric is a 
beauty.  They have made many modifications based on  performance and 
availability of tubes.
 
The two WE241's in the low level modulated stage have been replaced by  three 
833-A's,  The Machlett Triodes in the 5 kW. Doherity  have been  replaced 
with 1 each 6696 operating in linear mode driving the two 6696 tubes in  the 
Doherity Final 50 kW PA stage, one in the peak and one in the carrier tube  
position.
 
They also have the 407 from KOMA in Oklahoma City in their storage room for  
parts.  It is a newer transmitter than the WTOP Western Electric.
 
Dual heat exchangers for the water cooling system, it could run on one heat  
exchanger.
 
Also there was an old Collins 820F-1,  10 kW AM as their auxiliary on  site.
