I know the top circuit is a Klass circuit the scope add on circuit i have not seen since i found this which must of been a fair few years ago if not a decade or so .
I would think its all yours Klass ?
I came across this checking some old circuit print outs ...any case it needs a home here for others to try .

The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.

The top circuit with the bold lines in mine. It is also in the NBTV Handbook and there is a PCB for it. It is only a sync separator, NBTV video in and H-sync and V-sync out. The description is also on the http://www.nbtv.org website. Click Handbook, or Clubshop and you will find the full description.

Yes Klass i know of this Sync Separator i have made it in the past , i was thinking the circuits for the scope x y and z were yours too i think its ON1AU top of the page i was thinking it was your Amature radio call sign ?
I can't recall where i downloaded this as i have never come across your circuit with the XYZ circuits again ...a mystery !
