Neither lead to the cause. A stray piece of plastic in the bottom of the RF section pointed to one of the doorknob capacitors. Hey! There are two doorknobs switched into the Plate as padders only on 160m!   One of them is cracked and pieces are missing.

Glad you got it working Bob, but in case the doorknobs ever fail again, you
might consider replacing them with some of the Russian doorknobs available
on eBay. I have used dozens of them in my homebrew amps and like most
Russian equipment, they are built like a tank. Nothing subtle about Russian
stuff - it is made to last. FWIW.
