DIY Vacuum Tube Tester
Parameters:
Technical parameters of the meter are a compromise between the price and the number of tubes that can be tested. Based on the analysis of tube parameters that are currently available and often used, have been specified voltage and current ranges for power supplies:
- glow: 0..15 V / 2.5 A (temporarily to 3 A)
- Ug1 0 ...- 24 V / 2 mA,
- Ug2 0 ... 300V / 40 mA,
- Ua/Ia 0..300 V / 200 mA for increased accuracy in two sub-ranges 20 mA / 200 mA.
