Hi, I have an megadrive/genesis I bought as I am an enthusiast of the SMS music and the megadrive would allow me to benefit also of the 16 bit console audio chip.
I bought the excellent retrotink 2x-pro to upscale it’s RGB signal and did the audio mod (Genesis 1 Stereo Audio Mod | RetroRGB) to enjoy nice stereo music. I also got an everdrive X5 to put all those .VGM music in there. I’m very glad this project went well.
Only problem now, the audio is very weak and I would like to bring it to a more normal level without cranking up so much the receiver level. I see there is way to bring back that headphone amplifier level by doing further mod, but I’m not sure it’s worth it and I like that idea here of using an internal amplifier : Reddit - The heart of the internet . I think there might be good small pcboard that would accept 5v level that is readily available from the power supply. I was wondering if people have recommendation on a good, yet cheap and small amplifier I could use internaly. Maybe something similar to https://www.aliexpress.com/item/1005008059201648.html but I would need help to select transistor and make sure level are in good range.
Thank you
