Um have the diagram, but the wires on this do not match. ON the input side have an orange, rec, purple, blue and GREEN (what is this?) on the other side, 2 black (ac heater wires) yellow, grey, blue w/ white stripe (B+?) white and green (bias?) but then 2 brown wires ( not accounted for on the diagram

Also there is NO green/black centertap/ground. Now what is up here? Anyone have a clue about the 2 Brown wires? Also the blue wire w/ white stripe, is that a b+ wire? these wires just don't compute.

Please advise

Hey charvel pointy head, I had the same questions when I built my amp. Yes, your assumptions where right, the blue/grey wire is a b+ wire. White & green wires are the bias wires, & the other green wire is the centertap/ground wire.The two brown wires are not needed, I forgot what George said they were used for, but just cut them & shrink wrap them together. Good luck with your build

ok, at the risk of seeming stupid, which green is the center tap and which is part of the bias supply? Should I presume that the green on the input side is center tap and the green on the other side is the bias. I wish I could figure out how these wires correspond to the Heyboer tranny. Any help on that one?

Looks like both green's go to ground anyway, so I guess that solves that issue. Got another one I just discovered. check my other post.
