My genesis 2. crystal clear audio mod, cxa1645 region switch

Like the title says this system started out as a 15$ va 1 genesis 2 with the terrible ka video encoder that can't do s-video and horrible sounding audio. I bypassed the original audio circuit and built / installed tiidos amazing crystal clear audio circuit. I also bypassed the ka encoder and installed a cxa1645 video encoder kit giving me both the best video and audio possible out of a genesis. For the finishing touch I installed a region switch to play my japanese imports. Here's some pics and a demo video:

Awesome.

I read audio and saw the 8 pin chip there, is than an LM386?

Good to see some love for the Genesis.

It's fun being surrounded by Nintendo fans when you prefer SEGA.

4558d dual amp. Here's the awesome schematic made by tiido who designed the audio circuit:

And the instructions on how to install it

According to tiido this mod only works on asic audio models of the genesis 2. Probably just the va0 va1 and va1.8

Here's a video showing the audio quality from the same system before and after I built and installed the amazing crystal clear audio mod circuit.

Thanks. And yes that's the reason why I avoided doing this mod for a loooooong time.
