[BC] Gates VP-50 ?

[Robert Meuser]

The VP 50 was a standard plate mod 50K TX. The unique part of the TX was that it 
was water  - or more precisely vapor phase - cooled. This is where the VP 
designation originates. Plus side, no big blowers or building air handling 
required. The down side, if there is liquid involved, eventually there will be 
leaks. Also an external heat exchanger was a part of this rig.  50 KW was really 
too low a power for that kind of cooling. Numerous higher power transmitters use 
   some form of steam cooling, but very few are expected to run  24/7 with the 
lack of maintenance common with AMers here.

The VP 50 was replaced by the MW 50 which gave the Continental 317 C a serious 
challenge. The MW 50 and 317 C series were probably the best two tube 50K Txs 
ever built.
