Clever idea of Phil to use the hinged cabinet. Otherwise the only way to work on those Valiants is to pull the chassis out of the cabinet. That is one thing I liked about the Viking 2. You can open the top and bottom easily. I noticed that the two big mercury HV rectifiers are missing. Are there solid state rectifiers mounted underneath the chassis ? I remember the old 866's were a major PITA, often arcing over internally if they weren't given ample time to warm up. I remember solving that problem in my Valiant by putting a pair of argon HV rectifiers in place of the 866's. Much less problematic. Then I switched to a pair of those Peter Dahl solid state plug-in replacements. I kind of miss playing around with the old radios. Maybe the radio bug will bite me again soon and I'll get back into it. My main problem is I have too many hobbies and interests that I really love. But one day the radio bug will sting me back into the radio hobby. It always does. :)
