Ianr757 Posted June 11, 2021 Share Posted June 11, 2021 (edited) Hey guys, figured I'd post this here since it is technically an Atari 2600. I've been trying to mod my Gemini using a standard 2600 composite mod kit, following the instructions seen here: However, the video is super dark, as in barely visible. I tried removing certain components as described, but nothing helped improve the picture. Q3 is still removed, but it makes no difference in or out. Any ideas on where to start? Thanks.

Ianr757 Posted June 11, 2021 Author Share Posted June 11, 2021 Okay, so I added a 2N4401-ND transistor to the circuit, and now the video is much brighter. Is there any reason as to why this could cause issues in the future? Thanks. Quote Link to comment Share on other sites More sharing options...

I’m not familiar with the Gemini per se, but a transistor can act as a simple amplifier in the correct circuit; that’s why many very simple A/V mod board kits use nothing more than a transistor and resistor in the circuit.
