I have made
measurements on that tube with the following results:
CD47/GR-411 (used):
Ufiring = 140-145 V
Umaintaining = 142-148V (@ Ik = 25mA)
CD47/GR-414 (NIB and used):
Ufiring = 120-133 V
Umaintaining = 143 - 155V (@ Ik = 25mA)
So what we see:
Both will work on my power supply wich has 160 to 180 V
adjustable. If I would use a 250V supply, the losses would
increase. So I will go right with 170 Volts.
I can use it for my second and third CD47 clock.
