Default Re: Hedghog standards converter

Thanks Frank,
Just one final thought for tonight:- looking at the circuit, I can't see any reason why the Hedghog won't run quite happily without the modulator chips fitted?

A couple of people have had faulty modulator chips (these have, after all come randomly from China!). It would be handy to test the rest of it and monitor the video from the 'video out' connector on the 'scope. If that all works, I can then fit the mod chips one at a time and test them individually.

Is there any reason why that won't work?
