The wire are a standard color code. red B+, blue plate of the 27, Black grid bias, and green grid of the 71a's. Polarity doesn't matter on the green wires (doesn't matter which of the 71a's they go to).
GL When my pals were reading comic books I was down in the basement in my dad's workshop. Perusing his Sam's Photofoacts Vol 1-50 admiring the old set and trying to figure out what all those squiggly meant. Circa 1966 Now I think I've got! Terry
