I’m using an old Heathkit SG-8 that was my dad’s. I reworked it by replacing the original connectors on the front of the cabinet ...

About 40 years ago I used a number of pieces of vacuum-tube EICO and Conar test equipment that my father built from kits in the '60s when I was young. I eventually replaced almost all of them with GR and Heathkit instruments, but still use two of them (EICO 625 emission tester and 950A LCR bridge) - the rest are shelf queens. Some of them used the 2-conductor button mic jacks that were so common on EICO and Heathkit equipment in the '60s. I never replaced any of those jacks because 40 years ago parts jobbers were still common all over the country and I could get those plugs easily and cheaply for making custom cables.
