    Miller Dynasty 300 DX repair- summary/consensus?

    Miller WWWeb Readers/posters;

    DO I correctly understand that the consensus of experience and opinion is that a Dynasty 300 DX with a likely PC-3 board FAILURE is a "boat anchor" and not repairable?

    The unit will weld in stick/output, and displays in TIG Remote Mode, but will not strike an arc in AC (HiFreq) TIG, regardless of pulse settings on or off.

    I've read this board's history as far back as the threads seem to go? and the Miller Weld's forum on the same subject. Then hunted down and read several other forum's where this topic was returned in a Search.

    I don't want to ask for time to discuss, just the sense of the Board's posters- which I understand to be in the negative: this power supply from about 2003-4 vintage is now toast- or maybe a stick buzz box?

    thanks for anyone taking time to confirm or deny my conclusions?

    Cheers,
