High-voltage control discrete circuit for 15kHz RGB modified F520 and G420 CRT display / 15kHz RGB改造ディスプレイ 高圧制御

It is a replacement for the horizontal amplitude control IC and the high voltage control IC.

Please also refer to the service manual.

Never apply excessive anode voltage or cathode current to the CRT, even during adjustment.

A high voltage probe, oscilloscope, and experimental DC power supply are required for implementation. It is necessary to add a safety protection circuit to complete it.

調整中を含め、絶対にCRTへは過大なアノード電圧やカソード電流を与えてはいけません。

実施には高圧プローブ、オシロスコープ、実験用DC電源が必要です。完成には安全保護回路の追加が必要です。
