[TenTec] Capacitor Replacement on Orion II Power Distribution Board A9

[Marsh Stewart]

Barry,

I checked out the Power Dist Board A9 schematics for both the Orion 565 and
Orion II 566 on the Ten-Tec website. Here's what I saw for both:

C3, C4, C5 - 10 uF
C1, C2, C8 - 100 uF
C6, C7, C9 - 470 uF

I own both a 565 and 566 but have not disassembled each to determine the
values of the electrolytic caps actually installed. I am not saying WB2RHM
is incorrect. I'm just going by the schematics on the Ten-Tec website.

Now I wonder what the actual values are? 

Marsh, KA5M

My Orion II occasionally goes through the sequence of LCD display goes
dark followed by rig rebooting itself.  Am I correct in assuming I
need to replace the caps on the power distribution board?

WB2RHM posted this info on the original Orion (565).  Does anybody
know if this cap info is identical for the Orion II (566)?
