Hi Frank,
I've decided to take the plunge & have a go at building one of these. I'm sure it would be far more sensible to buy a built one from Stephen but where's the fun in sensible?
There are a couple of anomalies in the component list. These are C37 & C41. Both are shown as 10nf on the circuit but the part number on the component list shows that for 10 mfd.
Looking at the circuit, C37 couples the video signal into the modulator IC. Should both of these components be 10n or 10mfd?
Many thanks
Nick
