I am messing about with some Vactrols and I noticed something unexpected. I fed the LED of each one from a 9V battery through a 1K resistor. With the expected 1.9V LED forward drop that would push about 7mA into the LED.. Of the five Vactrols I tested, three were very close to 1.9V forward voltage drop but the other two were close to 1.7V. I then check them all on my ATLAS component tester which pushes an accurate 5mA through them with almost identical results.
Is this normal or do I have a couple of dodgy Vactrols ? (btw they are all the Chinese copies from Xvive)
Cheers
