Hi all,
I've made a circuit board for the RGB amp based on the one from the 1988 Japanese publication "PC Engine の すべて". You can find a printed schematic at http://www.gamesx.com/rgbadd/duorgb.php
I purposely compressed all the component spacings to keep the footprint as small as possible. The result is that the clearances are a bit tight, but you should still be able to assemble it by hand. All the components are through-hole, which makes it easy to solder by hand.
Best of all? It's CHEAP! $5 for the PCB. $3 for the components. Shipping included to the US. Here are some cool pictures.
Here's the bare board. The little extension at the bottom left is so you can solder in a 3x3 pin header that fits the back expansion port of the PCE/TG-16 (in case you wanted to keep it all external):

Here's the board populated with components:

Here it is fit into the top of the IFU shell, with the connector. As you can see, plenty of space to spare:

The amp in the top IFU shell, hooked up via jumper wires to the RGB sources from the IFU board. For those actually installing the in the IFU, I would suggest rotating the board 90 degrees from what is pictured and moving it closer to the ejection latch in the center:
