Give them 6 to 12 hours. This is what I have learned over time. In-13s are
more reliable at this than in-9s. On my kits I fing I get a 25% loss.

Forget to mention, that voltage od tubes stays around 100V all over the
time. In one point, when i am turning reference potentiometer tubes are

Hi again guys.

As I finally found time to continue with my IN-9 project I did small checks
according to your suggestions.
I connected 2 separate tubes from 2 separate current mirrors connected to
my HV PSU, and both of them light up same amount like before.
Current draw through HV PSU get dou
