Default Re: Telequipment D67 Fault

I can confirm that the 12 volt supplies are correct and the other tests you suggested seem ok. I get the correct time base driven signal from the output socket( front panel bottom right) I also see a small sine wave type signal at the GATE OUT socket but not sure if this is correct.
Is it safe to scope TR251 and TR252 (Unblanking amplifier)
It does look as if we are heading towards TR261 AND TR262
What should I see on CRT G1 and is this a safe signal to meter or scope
