[UK-CONTEST] Wanted 4CX350A / Eimac 8321 / GU-70B for 2M Amp

[Peter Walsh]

Hello,

Does anyone have a 4CX350A / Eimac 8321 tube or Russian equivalent (GU-70B) that 
is either used or new (must still work!)

.... Someone must surely have one that was purchased for that dream 2M amplifier 
that you saw a design for in the 1980's, but didn't build?  

  
I am looking for one as my tube is dead.  Please let me know if you have one 
spare in the shack/garage, or know of a likely (preferably UK) source?

Many thanks.

Regards,
Peter
