1000a OT wiring

Blitzen

TubeHead
Hi all,
I'm hoping someone can tell me what the color coding scheme is for 1000a output transformers. The transformers are labeled 410-5234 (A&B). The secondaries are black, yellow, and blue- I'm assuming black is a common, and yellow and blue are 8 and 16 ohms.
The primaries, however...blue, yellow, and orange leads. Can someone tell me what is what with these?
Thanks!

Blitzen,

Looking at a picture of the underside of the output tube sockets, it appears that blue and yellow (tube nearest the rear of the amp) go to the output tubes, so orange must be the B+ connection.
