[TenTec] Orion II and new 2K-FL amp

[Michael Tortorella]

John, last time this happened to me it was the trimpot on the regulator
board had gotten dirty.  Cleaned and exercised and that solved the problem.
Hope this helps.

Progress report... or lack thereof...

I was ready to take the next step with this amplifier when my primary 
station power supply, an Astron VS-35M, failed. Zero output. I had 
replaced the bridge rectifiers in 2012 and they're OK --- 21 VDC out of 
them. Problem is somewhere farther downstream. I posted a request for 
help on the eHamnet "repair" forum and have one reply so far.

QRT for a while unless I drag out a little 12v supply and fire up the Scout.
