This may not be the correct forum for this as it seems to be dedicated to PC gaming, but i will give it a shot.

I am looking to buy/construct an encoder capable of taking RGB from a JAMMA based arcade board (15kHz R, G, B, comp-sync & GND) to PAL composite or s-video for display on a standard TV with these inputs. This is similar to a board made by JROK and sold in the US. Essentially, it consists of a single IC (Analog Devices AD725: RGB to NTSC/ PAL Encoder or similar) and a few other minor components.

I am looking for anyone in NZ that has knowledge about this type of converter or where i can source the IC at a reasonable price (i.e. not specifically shipped from outside of NZ).

The other alernative is to feed the RGB straight into the guns in the TV box, but i am still wary of this approach (would rather start with non-descruction approach).

Any help well recieved.

Go into a scart input, or alternatly there are scart to component converters easily available, a simple sync encoder will take the H+V syncs to the composite sync that scart needs.

If the TV I have had a SCART input I would not need to do anything, but mine only has composite & RF inputs, so a simple SCART soluation would not work in this instance.

Get another off trademe, I got a 29" with scart for $10, the smaller ones seem to go for a little more for some reason.

You really dont want to reduce yourself to svideo or composite because the colourspace is so small compared to RGB.
