[TenTec] 566 A9 Board Re-Cap

[Kim Elmore]

I just finished replacing all the capacitors on the my Orion II (566) A9 
power distribution board and it wasn't all that bad. The ROHS solder is 
a bit more troublesome than the older 60/40 solder, but it's not 
terrible. I, too, had trouble clearing the solder holes and in a couple 
of cases had to "walk" the old capacitor out and the new capacitor in by 
alternately heating each lead. But, even so it went smoothly, took a 
relaxed hour to do, and my work passed the smoke test with flying 
colors. The worst part was getting the rig out of its operating position 
and then getting it back in.

Upon inspection I found no evidence of any problems with the old 
capacitors, but the rig doesn't have nearly as many hours as some of you 
report. This way, I'm pretty sure that I won't have problems for as long 
as the rig lasts -- which I hope is a very long time.
