since my PT doesnt have white or green wires on the primary side - im wanting to find out if im assuming the color scheme correctly.

Almost, the two solid blues are bias. Blue with reddish stripes are 400V taps.

well thats where i got confused i figured both taps would be schemed together as far as plain colors but then it makes sense that the blues are bias....but u are ya sure Steve?

plain red = 500dcv tap
blue bias
blue/purple is 400dcv tap
red/yellow CT

Just put one in, so yeah that's how it was wired. Actually it may have that PT in the new 100 watter instructions Andy redid too, now that I think about it.

Of course you know how George likes to keep you on your toes with color codes

Yes, that amp is on my bench being modded right now -- blue w/stripe are the low voltage taps, solid blues are the bias.
