Hello Martin,

Do you have 3 422 scopes or 3 intensity pots? Seriously, thanks for the comment, I will look at that pot. I took the covers off for the first time today and checking the power supply found about -550V on the HT test point (crt grid). I'm not in the workshop just now but I think the expected value is around -1350. I will get back onto it tomorrow.

Regards, Frank.
