Hi Chuck, I got the scan, thanks a million
At first glance it looks like this might be more correct than the others, I will have to dig into it later, tonight hopefully.
I stopped at the Lectronics store and picked up a new Detector Diode just in case. I tried replacing it in the past but I only had a used one.
If that's what's wrong with it I'll have to smack myself upside the head for being a dummy.
