RGB amp

I was referring to the schematic fraggore posted unfortunately!

steve is aware of that, he is making sure everyone else is.

lol
that one works without mod too

While the other NJM circuit posted on here would work as is, I have always found each system needed a little "tweaking" when it comes to RGB. The one I use for Duo / PC Engine is a slight variation, however I had better luck removing the 1M ohm resistors on the input line, when I used it the image was too saturated, but again this was using an Atlona box, for some of you it might look fine depending on what converter box you are using.

interesting have been looking for  good amp you got some values for the components.

i also have this amp i was thinking of making.

the main difference in this circuit is the 1000pf caps on the output lines, depending on the application 1100 or 1200pf can be used, and this helps filter out things in the signal (and as a result reducing jailbar effect.

Didn't see this reply!

I'd actually be using it on a CRT television.

Currently considering the THS7314 method instead of this one, although this one seems to be tried and tested. Hmm.

The ths one is tried and tested too.  I've built both the ths amp and ths amp.  Both do pretty much the same thing.

So either is good? Do you have a preference at all? 

Also I have a Core Grafx 2 - is taking RGB from the expansion port as good as directly from the video chip?

My preference would be the ths one just because there's less parts involved.
