Well, maybe I have someone's attention?  This past weekend I picked up a 
Transworld UPS500 28v DC power supply that I wanted.  Along with this 
power supply was the accompanying TW RA400 400w HF linear amplifier 
unit.  (No R/T unit, however.) The amplifier is said to /probably/ need 
some new output transistors, otherwise its in excellent condition.  The 
thing is, I do not need this amplifier.  The amplifier requires 4 output 
transistors and, serendipitously, I have 4 ea. MRF422 28v 150w output 
transistors that could be used in this amp if the installed output 
devices are, in fact, all bad.  Does anyone out there need such a unit?  
If so, I'd be pleased to receive an offer for same, and include the 
transistors.  It is heavy!  I have the mating power plug (only) for the 
amp as well as a c_omplete manual set_ for the R/T unit, the amp, 
antenna tuner, and power supplies.  Or, maybe I should just sell the books?
