Thanks to all for the many responses and suggestions on the problem I was 
having with my Orion II.
The problem is now fixed, and just wanted to provide an update here.  I 
talked to the folks at Ten-Tec, and they first sent me two capacitors to 
replace C6 and C7.  After replacing, I still had the same problem (5V 
cycling on and off).  Then talked with Ten-Tec again, and they sent me a 
complete new Power Distribution Board - A9.  I replaced the original board, 
and all works fine now.  Sorry, I don't know what exactly was wrong on the 
bad pwr board.  I have mailed it back to Ten-Tec.  The capacitors C6 and C7 
on the new board were still 470 uF - 16V, but they were larger than the ones 
on the old board.
Thanks to all here, and to Ten-Tec Service for the help with this problem.

73, Tim - N3XX
