What's a  Lil' Rascal?




+++++++++++++++++++++++
 
The CCA FM2500R was a 2.5 kW single tube transmitter using the 5CX1500  
pentode final tube driven by CCA FM-40, 40 Watt exciter,  The transmitter  was 
mounted in a 19 Inch rack. Too much in one rack. The cooling of the  tube was 
difficult. Plate transformers had a high failure rate.
 
Also the 5CX1500A in FM Service as a single ended 2.5 kW. transmitter does  
not have the greatest record in any companies Transmitter.  It was  originally 
a good tube but later on the tube life went to heck as the price  climbed a 
couple of hundred dollars.  I believe it was actual Econco who  suggested the 
solution which ended up being the 5CX1500-B tube.
