A friendly recommendation: you should also change out the electrolytic capacitors while you're in there, since they inevitably dry up and cause problems, and with a unit that old it should be done as a matter of maintenance. They aren't too expensive. Otherwise, this was very neat to watch!
Very cool mods. My buddy picked up a similar unit that was built from a kit likely in the 1960s. We tested it and it functioned flawlessly but could benefit from a new powe cord and the digital meter.
But there has to be a downside or limitation, because the meter circuit will require some power, and with only two leads that means the meter cannot operate down to 0V, otherwise it would not be able to steal a few volts needed for its operation (unless, of course, the meter uses a battery for power).

nice 1990 Micronta multimeter. I still use mine too.
Thanks for sharing this!
liked your very useful video but how about installing a current digital display too.
Pretty sure that is a variac/auto-transformer, NOT a potentiometer.
0 to 30 volt with two leads is everywhere ready available.

@@youtuuba Yup, not to be used for precision work only useful for motors ed. btw, I wouldn't use Chinese crap anyway for electronics. :-))
