Default Re: System A Ch1 modulator using MC1374.

I built the ETF modulator on a breadboard three years ago to use with a PC graphics card project. It works so well it's still in the state you see it here.

I have started to build a slightly more presentable one on perforated project board, I must get round to finishing it.

Anyway, my point is the absence of a custom PCB shouldn't put anyone off.

Mine is tuned to B2, the free-running oscillators are no problem, set and forget. I didn't bother with the output filter, I don't think David did either.
