I was testing nixie using variac and a mastech meter i just recently bought.
so i had a 22k resistor to limit current from going above 10ma (the spec of my nixie says current 10ma).
The problem is, after i reached the desired voltage on variac, where all digits glow just the right amount ,I went on to measure voltage on variac , I got the result as follows-
117v on ac output
50v on AC setting of meter (dc output)
104v on DC setting (dc output)
the problem is ,even after rectification, why is there still 50v AC
is one of my diode shot?(which would have definitely lead to magic smoke) (ill check soon after this post)
here's a drawing of it
