This is a pretty nice Triplett 3423 Tube tester which I've acquired many years ago. It's a very decent tube tester that tests Emission, Shorts, Gas, Leakage; etc.
In case you don't know, the 3423 is the 2nd best lineup of tubes' emission tester Triplett ever made while 3444 being the top of the line big brother to the 3423!
I've not used this in many years because I am now using Hickok Cardmatic Tube tester. It is working but may need some service and recalibration for daily use. I don't know for sure since it is vintage item and sold as is.
While I was using it, it is very fairly accurate tube tester. I've replaced some electrolytic caps and some tubes inside this many years ago as precautionary measure. I also installed inline fuses on both live and natural side of the AC power cord.
I've just tested it with both 45 tube and the 12AU7 tubes just now and the test results seem to agree with my Cardmatic tester.
The tube test chart rolls nicely from the start of the chart to the end without any problem and it's in very nice condition.
Having said that, there are some minor known issues that may require some Total Loving Care (TLC)!. Line Adjustment is a little flaky occasionally but powering it ON or OFF or flipping the Tube Strength lever a couple of times seems to clear that up. I think it may need some cleaning on these mechanical parts or some caps or components may need attention which I don't know or not have time to look further. Or it may simply needs some calibration! The acorn socket may need replacement but who uses them anyway?
It comes with reprinted user manual, additional tube supplement chart, calibration guide, circuit diagrams, and a very rare Triplett Tube Tolerance Computer Chart which is pretty neat!
The tube tester looks very good and mint internally but the outer case shows age!
It costs a whooping $199 in the 60s but I am asking $400 firm for this nice tester.
This tester weights almost 20lbs unpacked!
Paypal fees and shipping fees will be added based on your location.
