Tubes are tested by Hickok 539C vacuum tube tester. This tester was precision calibrated by Roger Kennedy to improve measurement accuracy. 83 and 5Y3 tubes were replaced by Solid State rectifiers to minimize calibration drift in the tester.
All tubes are installed into an actual audio circuit to screen them for internal tube noise/microphonics. This is especially important with the 6DJ8/6922/7308 tubes.
