This listing is for a Superior Instruments Co. TV-11 Vacuum Tube Tester. This listing comes with tester, the condenser test leads. No user manual but it can be downloaded from the internet.I\'ve added a printout of the tube chart supplement.
This tube tester was updated by replacing the capacitors with new ones. The resistors were checked and replaced as needed. This is one of the earlier models that came with the RCA 954 tube used as a rectifier instead of a selenium or diode.
The TV-11 was fully tested and works well. The line can be adjusted with no issues.The test tubes were priorly checked in a good dynamic conductance tester. The first couple of pictures are from good 6GW8 tubes and the next one is from a bad 6GW8 tube. Next test is from a good 6V6GT and lastly a good 12AX7 tube was tested.As it can be seen on the pictures, the good known tubes tested good, and the knownbad tube tested bad.
The tester checks for shorts as it should. The condenser (capacitor) leakage test works as expected. The noise test also works fine.
Cosmetically the tester is in very nice condition. The wood case does have a good amount of wear to the veneer (see last pictures). Please carefully inspect pictures as they are part of the description.
