I'm not sure which circle to post this, but thought I'll try it here and also in Audio Central.
I have a very early Hickok 534 tube tester (roll chart says 1952), which does not have a 9 pin miniature socket. Does anyone have a 9 pin adaptor that Hickok used to make for the early testers to sell? Since I mostly test the 12a family of tubes (including 5751, 7025, 6881, 5814, etc) and 6BQ5/EL84 tubes the tester is almost useless without the adaptor. Thanks.
