Simple Question
#6

From The Philco Serviceman, May, 1934, p.4

Red......................Filaments and odd wires

Brown...................Cathodes and grounds

White...................B+ and screens of output pentodes

White & Black..........Plates (Wht with blk tracer)

Black & White..........Plates (Blk with wht tracer)

Green....................Grids and screen-grids

This scheme was not strictly adhered to in many following years, it seems and not post-WWII.
Probably valid up through 1936-37 model years, at least.

No revised color codes found in any of the later Serviceman bulletins that I have.

Chuck
