658 & 648 |
Diagram of the pin connections of
a 4, 5, 6, and 7 pin socket adapter for use with Jackson 648's and 658's.
This diagram provides the information a person would need to build a socket
adapter for the more modern 648's and 658's which don't have sockets for the
older tubes. The adapters themselves are fairly rare, but easy to make, with
this information. Jackson used an odd channel scheme for pin connections, so
it's not as simple as connecting pin 1 of a 4-pin socket, for example, to
pin 1 of something the tester has, like an octal socket. This adapter would
use female 4-7 pin sockets, and a male octal socket (which plugs into the
tester's octal socket). Compliments of Erik Knutson. |
