Ok guys. I found that I have a Triplett Model 5 type 2 loop tester gathering dust. Looks like the rotary switches could use a shot of contact cleaner otherwise I can't see anything wrong with it. Anybody want it? Free to a good home. If you can't use it for it's original purpose keep in mind that it is a digital multimeter, a tone generator and makes it easy to measure POTS loop current and voltage regardless of whether it's copper or from a cable modem.
