Another Soviet plugin: 7CT1N curve tracer equivalent §Á4§³-92


 

It was with some excitement that I unpacked today's new acquisition. From a surplus dealer in Ukraine, via some helpful friends in that country, I've got my hands on the §Á4§³-92, the Soviet version of the 7CT1N curve tracer plugin. in its original transit case with an almost complete set of adapters and its original manual and calibration certificate dated 1988! It's not new old stock and has definitely been used, but the seals on the plugin are intact.

There are five different adapters which fit on the front of the plugin, one for two-lead devices and the others for various transistors and FETs. They all have two buttons for comparing devices, and little plastic lids with a microswitch to enable the tracer when they're safely closed. The only bits which seem to be missing are a couple of connector blocks which seem to have something to do with the calibration process, but I'm not too worried about those.

I have to say that the Soviet makers have the edge over Tektronix when it comes to the sheer robustness of the packaging. It's a plywood box with steel corner protectors, lined with polystyrene and foam to fit all the parts. The whole thing weighs about 10.5kg (23lb).

It'll be fun learning to drive it, and it will be really useful in the lab, too.
