Amiga RGB to S Video & composite adapter

[Wingnut]

Looks like you built the same circuit that I did.  I had the same problem and I found that the output pins to the s-video jacks were reversed.  Composite jack worked although not as clear as the s-video.  Good luck.

Read your post and switched the outputs. I was in a hurry so I used jumpers to switch them. Pulled the cable from the TV to run a quick check. OK everythings connected again. Pluged it in the 500 and turned the computer on. .....Nothing.....oops..... I neglected to plug the s video cable back in the TV. Powered everything down and plugged it in and IT WORKS. It's time to heat up the soldering iron.

I went back to the ADF for the AD724 chip and if I am reading it right they have the schematics wrong for that part of the circuit.

Thanks Wingnut.

Your quite welcome and yes I also concluded the leads are reversed from the ad724.  I built the circuit externally so that I could move it to any Amiga and not have to worry about finding an old 15khz monitor.  Mine worked very well with a cheap lcd (Maganovox TV) and A600.
