use this link to look up semi's
http://www.nteinc.com/semiconductors.php?a=12 I think what you are working on is in the US a PVM monitor. Yours may be close to a PVM1200, that may help you. There are many on this list with experience with them. Good Luck 73 Zeno LFOD ! |

It looks identical to the KV1212 I had.
Never had a problem with the power supply, but it had bad 'lytics in the PC corrector, where it was distorting the picture on the right. The vertical lines in the picture were curving to the right. I sold it when the CRT was showing it's age. |
