[SECC] 3-500Z

[k4bai at worldnet.att.net (John T. Laney III)]

Hello all:  Anybody need a 3-500Z?  It was donated to the Columbus 
Amateur Radio Club and I have been tasked with trying to find it a 
home.  I no longer have an amp that uses them (I had a Drake L4B that 
used two of them for many years).  We really don't know anything about 
the tube.  I assume it came from an estate.  We could probably arrange 
for you to try it out and see if it works OK before you make an offer.  
Anyone interested, please let me know.  Thanks and 73, John, K4BAI.
