Hello, unfortunately no test values for signal diode tubes are published. You can try this little test circuit as shown. The 6.3 AC voltage source might be the heater voltage of the tube. Across the resistor R1 (100 kΩ), parallel with a capacitor 1 µF, you should find a DC voltage from about 6 to 10 V. Just test on both diode units, compare it with other signal diode tubes, such as 6Q7, 6AV6, EBC41, etc. good luck, Best Regards, |
