>> Thanks to all that responded with assistance ideas for the AL-82 no-output on 160m. I had concentrated on the burned plate choke and the load padder wire that fell off when touched. 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.

Yeah, by all means. If ya wanna pay too much, buy them on Ebay.
If you'd rather get a proper deal and help a worthy cause at the same 
time, then get your Russki stuff from Dr Alex, UR4LL.

See http://www.ur4ll.net/

The profits from his sales go to the local hospital, where he is a 
leading figure. By buying from the doctor, you are getting the best 
possible service, price, advice and quality and you are helping improve 
the world for many thousands of people.

Check his site often. It is updated regularly. Catch him on Skype and 
he'll show you your stuff, live on camera, as he weighs it and quotes 
the postage for you.

73, Alek
