Default Re: Pye VT2 EHT problems

I've spent most of today working on the Pye and its beaten me yet again.

Thought I'd solved it as I discovered a 2.2k resistor which should be a 2.2m. (R27 on trader sheet) I'd replaced this in the past and must have read the value wrong. Replacing this with the correct 2.2m has locked the frame scan but the picture information is all wrong again. Here's a pic to give you an idea - I'm getting a double image vertically and loads of flyback lines so am I right in thinking the frame frequency is wrong?
The line hold appears to be locked ok. I have been through all the resistors, all the caps are new and I've ran out of things to try. Can anyone advise me please? what area do I need to concentrate on.
Would the fault be in the frame output or the sync separator? I am totally stuck with this set!!!!
