[TenTec] Pegasus DC Input Issue

[John Huffman <hjohnc@gmail.com>]

Through various misadventures, the DC input relay on my Pegasus will not 
engage when power is applied, mostly.
I suspect the two transistors or the one diode near the relay coil.  
Perhaps this symptom would give one of you a clue to the component(s) I 
should replace.
The DC input relay will not trip and power up the Pegasus using a 
regular station 12v power supply.  It will trip and power the Pegasus if 
I use a battery for the 12v.  I am guessing a grounding issue here, somehow.
Any suggestions greatly appreciated.
