Klausmobile Tube Tester Files
Made in Vinniza (Ukraine). Surprised? 6J5P, 6J9P, 6N3P, 6F4P, 6K13P were also made there. The tube has big, EL84-style plate.
Triode mode, grid 3 at cathode
| Standard specifications per each triode | |||
| Parameter | Maximum | Operating Point Pentode | Measured Triode Mode |
| Ua, V | +250 | 200, 200 G2 | 200 |
| Ug, V | +250 G2 | -2.4 | -2.0 |
| Ia, mA | 25mA Cathode | 8.5 + 3.5 G2 | 10 (P+G2) |
| Pa, W | 2.5W + 1W G2 | 1.7 + 0.7 G2 | 2 (P+G2) |
| Gm, mA/V | - | 15.5 | 16 |
| Rp, kOhm | - | - | 73 |
| Mu, V/V | - | - | 4.5 |
Note: Disregard Gm/Mu/Rp values for extreme Ua values, as these are skewed by the tester's power limit (obvious in the first curve set)
Legend: White curves: Ig<5uA Yellow: 5<Ig<20uA Red: 20<Ig<300uA. Measurements terminate at Ig>300uA
