I got a socket from a ham in Slovakia (Homemade), Branko S52V, and he did
a very nice job on the socket with copper finger stock. I attached a small
picture. Have not yet of course used it but the tube fits very nicely and
while this socket would not be useful at VHF/UHF it should do very well on
HF. Nicest thing about it is that I did not have to make it as it looks
like it took some considerable effort.
