TT-1 W/TA-1 tube tester set

This is a very good quality tube tester. I tested only 12AX7 and 12U7 tubes and it seems to be working fine, but must be recapped before using it. Youtube has a lot of good videos showing how to recap. 

Everything looks to be original. The chart turns smoothly. The tester is in very good physical shape with only minor blemishes. However, the case is not in very good shape...the wooden frame is good but the veneer needs to be reglued. 

Included are the manual (for TT-1-A) and an updated tube chart.
