Byron,

Thanks for your reply.  I have that board out of the rig already, and when my 
wife quits bugging me (it's Valentine's day so I can't ignore her) I'll get to 
checking that diode and whatever other components I can.  I suspect it's 
something like this as well.

Hello
 If voltage drops down to 5 volts is drawing a lot more than 6 amps Hihi
The only thing  I can think of is Polarity  protection diode.  However I did 
buy a Orion that the circuit board was toast next to the molex plug .

 Be very suspicious of the power connector at the back of the Orion. I had to 
change mine for power poles. The connectors are well known for causing problems 
like this.

Thanks Bernard.  I already have.  I checked on 2 other power supplies with the 
same result.  The LCR also indicates that the repairs I made on the A9 board 
are still sound.  While I have checked continuity on the power connector, I'll 
give it another look and make sure it has a GOOD connection.  However, with the 
observed amperage draw I suspect that the power connector is fine.

I would try another power supply and check the A9 board (it may have failed 
after you rebuilt it).

I would also check the integrity of the power connector.
