Sorry Steve
I was not blaming your circuits or any thing using them here as i like them ...it really didn't sink in till now about the ramp needing to be as mentioned i can't say i have come across this before perhaps i need a inverting or non inverting opamp after the sawtooth generator ...i think i need to have a look at Klass's sawtooth circuits may be if i ask kindly he might post them up .
I have a deflection circuit working apart from its a bit wonky at the start of the scan i wanted to see if it could be improved on since i only have one of these crts i don't mind trying different circuits on it as once its done its done like a trip you don't want to see finished ... i am not good at designing stuff so i do tack this on to that in a trial and error way i have to learn by my mistakes what works and what doesn't .
