Vintage Metal Dual Lab Use Scientific Rheostat - 10K Ohm
Tested - one rheostat works good and tested as 10K Ohm. The other appears to be 1Meg Ohm
but kind of flakey in operation. Perhaps wiper terminal needs deoxidized. I think they are both supposed to be 10K Ohm.
These are rated 300V at 0.070 Amp
Useful for tube amp testing. Looks great as a display item. Very fine condition for it's age.
