Arcade Otaku - アーケード オタク

Does anyone know of a similar device to http://www.ultimarc.com/vidamp.html" , but with a DB15 on both sides? The Taito JVS/AMP IO doesn't have one on board, meaning if I use it with a monitor expecting 4v RGB everything is washed out. Looking for a neat way of putting an amp in between a PC and the I/O without needing to cut cables.

Still looking...

Hmm, that is the format I am after however it is a signal mangler rather than an amplifier.

Guessing I will have to build one if I ever need it.
