I feel there's a void for this device. A few worthy options exist but they are pricey and difficult to purchase, especially for people outside of the USA.
So, I'd like to see if we can do something about it and create an open sourced PCB so that a PC Engine RGB amp with accurate video output levels is accessible to all.
There's not much to it really, components and circuitry is dead simple and I've got a fairly decent grasp of the values required but would love some input from anyone whose spent some serious time on the subject. I need to dig through some notes I have saved somewhere from Tim Worthington who provided some starting values of the resistors / capacitors required to get as close to 0.7vpp as possible given the odd output of the Hudson video chip.
THS7374, voltage divider and 0.1uF decoupling caps on input - DC restoration caps and impedance resistors on output.
Anyone have any advice, information to share?
