Ok bk to 625 hit it with power had power all over but dead picked up an oscilloscope by accident played with it never have an experience with one got it to do squiggly wave forms somehow so in the months before have changed the jfets the igbts so was (not under power) just fishing really found some really bad solder joint. Loose not tight. Fixable get to q4 fet 1 line dead so ordered some more traced dead line downstream seems alright got wave ill change it out when it arrives an see if that makes a difference all other circits seem okie dokie then I can have a comparison ole 625 against 45xp memories a terrible thing I think the miller was a cardiac the hyper s don't get that maybe world changed anyhow back to wasting on parts check back in later
