All 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.

I also perform listening tests on these tubes using Music Reference RM-4 pre-preamp (moving coil head amp), which has 30 db gain. This unit uses two 6DJ8 tubes (one for each channel). Each channel uses both sections of the 6DJ8 tube.
