Nobody who has an idea ?????????????

It switches off because it is too bright.

You need to find out why it is too bright check G1 G2 & cathode levels.

Any idea what the correct levels should be?

Which version of the S7500 is it look for compaq extended model numbers like PE???? or CO???? etc.

Rich

Hi, model is S7500, PE1162T

Hi I do not have info on that one but in general they are;

Cathodes 45 - 70V
G1 approx 115V negative of the cathodes i.e. cathodes at 65V then G1 = -50V
G2 = 400 - 700V
Heaters 6.3V DC
