Title: PC Engine Duo RX RGB amp?
Post by: Piratero on January 15, 2012, 09:05:03 PM
Hello everyone.

Would the THS7314 RGB amp for the N64 work? Has anyone tried? I have a few THS7314 chips lying around and wouldn't mind building one for my PC Engine.

Otherwise, what is the preferred  RGB amp? Any recommendations?


I've been Googling (apparently my Google-fu is not up to par) and I haven't been able to find the tutorial where it shows you step by step how to remove the 5-DIN connector and replace it with an 8-DIN connector.


Thanks everyone.

I believe it'll work with the PCE, the RGB cable that I use with my modded Duo-R has a THS7315 amp built in. For the DIN jack replacement, there is a detailed video that shows you to do it: PC Engine(turbografx) DUO-R RGB mod soldering work (pt 1/2) (http://www.youtube.com/watch?v=3cg6V3qLEh4#)

Did you build the RGB cable yourself?

Just out of curiosity, how did you go about building your THS7314 circuit?

It's extremely small and really the biggest problem are the resistors.

SMT to DIP adapter boards exist for the THS7314's SOIC-8 form factor. See: http://www.sparkfun.com/products/494 (http://www.sparkfun.com/products/494)

you guys have been extremely helpful!

I need to build a SCART->DB-9 connector first.

I feel like the prices are a bit steep on eBay. I'm looking at:

To be clear, I'm in the United States.
