In that case almost any tester that already has the sockets you need that fit your tubes will suffice, if the tester is in working condition. Too many brands and models to mention fall into that category. So my advice is to shop for price and a reputable seller rather than brand and/or model...
The sockets needed to test 12-pin sweep tubes, along with 9-pin Novar tubes and also Nuvistors, are installed on the bitmatic's control box (see picture above). No adapters needed.
Thanks for the nice write-up, nomadradio!
