Before writing my project, I don't know if an amplifier like this really exists, I actually looked for one or wanted to buy it and never found it, so here I go. A while ago I realized that the pcb boards of midway games like Killer Instinct 1 and 2, Mortal Kombat 1,2,3,4 lacked color and sharpness, I thought it was my imagination and made a comparison between mame and the original hardware and the original hardware lacks RGB amplification at least on the Wells Gardner K7000 monitors. PCB boards like neo geo or cps1, cps2 and cps3 do not have this problem with Wells Gardner K7000. So I was annoyed by this situation and looking for a post from someone who realized the same problem and not finding it, I decided to create an RGB amplifier that improves the RGB signal and now the colors are more intense and the image looks sharper. I did not have in mind to sell them but it was mandatory to obtain the minimum of 5 pieces in the order of my PCBs so I will put 4 for sale in case someone is really interested in improving their image quality in wells gardner k7000, I don't know if this helps for other chassis models. Here is an image of the assembled PCBs, and some comparison images with and without amplifier, it is really difficult to get a good quality image with my cell phone but I assure you that the differences are very noticeable in person.
