:dualthumbup: Will send a pcb this week, will do a parts list for you as well soon.. There are a couple resistors of slightly "unknown" values due to untested changes.. So you may need a couple of presents to fine adjust them..

A quick question.....

I've just got a 2600, no idea if it works, not the woody kind and plugged it in yesterday. I couldn't get it to tune into my LCD TV, I take it this is why you guys have gone to Composite mods?
If it ain't broke, test it to Destruction.

My LCD works OK with RF. Just going with composite for better image quality more than anything.

How did you get on with the composite mod? My 2600 jr doesn't like my LCD tv at all.

Hey Chris, I'm trying to push myself back towards getting some Atari projects done, and this is one of them.

I've managed to source a couple of the MAX7453 chips and the other discrete components, but the FMS6146-D is something else, and I can't find it at any of my usual sources, can you advise on a supplier please?
