| Success:) color classic analog issue |
Posted by: imactheknife on 2025-12-07 05:29:52
So i had a friend who had spare lc 575 analog boards. We tried everything to get his original color classic board working but nope, just didn’t want to play nice. So we did the Japanese mod and converted the lc 575 to work in a color classic. Also, the color classic is now booting natively into 640x480. Next will be to hook up speakers etc. but cool mod. |

Nice, did the 575 fit and need many adjustments to drive the CC CRT? |

Nice, did the 575 fit and need many adjustments to drive the CC CRT? No, the lc 575 analog had to be cut down pretty good, even to get case back on. The chassis has to be cut down too. After it was all done and working i had to adjust a few of the pots on back of analog boards to get screen looking good and right size but nothing else besides brightness control and focus pots on the side of analog. Colors are great, everything is stable too |

Also hooked up two speakers and put my color classic ii board in it and now shows stereo sound and has thousands of colors compared to the 256 on original color classic logic board. So going to leave my color classic original and put my color classic ii board in the modified unit now. |

Did you have to replace the flyback transformer? I sort of remember that you had to transplant the original CC EHT to the 575 AB to make it work. |

I’ve tried a 575 flyback on a stock CC AB and can confirm it’ll work, but you’ll never get the image adjusted properly. |
