Trimmer for crystal frequency fine tuning

Open eluancm opened this issue 2 years ago • 0 comments

A trimmer capacitor with a reasonable range instead of a fixed capacitor on the TMS9918A pin 40 would be useful to fine-tune the frequency and get good colors.

On one of my aged TVs, I need to put a finger on this pin to get any colors, regardless of fine tuning.
