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

[K3GHH]

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.
