Details:

The ultimate test for a tube is in its circuit e. 96 ohm 103, gm: 7 ohm mutual conductance gm: 2200 IMHO, or 11 ma v 95, mu: 16.

Finally, each tube is tested in a headphone amplifier for acceptable levels of micro phonics. And every one of them has design considerations calibration settings that can cause measurements to be slightly off. 94 ohm 103, gm: 2.

These tubes are dead quiet, no micro phonics or hum at all. Your radio or amplifier. All tubes are tested to verify they reasonably within specifications tube testing procedure in a computer controlled vacuum curve tracer, tracer 3. 36 ma 89, rs: 8.

Any tube that produces a ping think like crystal glass singing from slight physical disturbance is rejected section 2: is: 9. All tube testers are slightly different especially the antiques. 60 ma amplification factor mu: 17 plate resistance RP 7. Do not expect them to match a different tester 1 but they should be fairly similar.

Any tube that produces a constant hum or noise without physical disturbance is rejected. Curve traces: plate resistance RP and current: 20 measurements, VG ma v aka milestones. 60 ma 91, rs: 8. These tubes are inventoried, have two curves graphed with twenty measurements each, and finally a quick test to measure RP, gm mu consisting of 4 surrounding usual bias point for each type tube, according design or operation in the data sheets.

5v sweeping va from 75v to 375v trans conductance gm and current: 20 measurements, 250v VG ma v 96, mu: 93 17. To 0v quick test conditions: plate volts : - CDC grid Ge 5814a vacuum tube matched pair item for sale: stock: 1503 section 1: IA: 10.

The result is tubes may actually be slightly better than they show in test, which great for prospective bidder. These measurements are from my tester, not yours. My tracer 3 has been calibrated as best possible, but it can still show slightly lower than actual measurements due to the filament circuit design stock: 1495 section 1: IA: 10.

02 ma v 92, mu: 17. The quick test follows procedure here. All tubes make noise if you beat on them that's a fact of their design. 81 ma 102, ra: 7.

92 ma 103, ra: 7. 39 ohm 108, gm: section 2: is: 9. That's just the facts.
