Picked up one of theses a while back to restore. I was lucky as this unit was in very good condition. Seems like most of my recent ebay purchase lately are not the best.
All Ele caps and resistors were replaced, everything else cleaned and lubed. Just need to go through the test leads and calibrate.

anyone know are these OEM? The slip collar wire connection for a test device seems odd?

I don't think so. I once had the TF151 purchased new and the probes were one-piece molded.

I like your TR139. The TF151 was too complicated for me, needing to look up every device I tested or a cross when I couldn't find the info in the data book included. Sold it on years ago.

Here's an ad and the manual for yours.

Finished calibration, test leads I redone, but don't care for them probably change them out.

There's a user review of it on page 60 in the August 1968 Radio Electronics. He liked it! :D
