There are a few 6V vibrators for sale on QTH.COM, look
in the tubes, etc. That's a early cold war spy set, is that
correct? Outstanding performer on receive and transmit,
it will literally load into the proverbial wet noodle.
I have a complete set, but never did try to find the vibrator
for the empty socket.

Jim, its not a cold war spy set, it's just a British military receiver that
uses directly heated tubes (ARP12's and AR8's) .
Thanks for the info on the vibrator.
