11 pin was used by relays and for power supplies, such as the Heathkit HP-23
for the SB series of radios.

6 pin socket & plugs are the ones normally used with older Leslie speakers
(like 147 & 122) with tube amplifiers, that attach to Hammond organs.

8-pin was the popular octal used for a number of subassemblies, relay
sockets and cables.
