OK, I think I've answered my own question, and found a Philco Bulletin 128A on eBay, which I will scan and upload to the Phorum once I receive it, since it appears we don't have one here.
However, the schematic is for the 22L, which uses the same chassis as the 71B, and I think this one is the same as the pre-Code 125 71 series, which doesn't show the new tone control and capacitor off the 42 tube plate. We'll see once I have the full bulletin in my hands.

"Why, the tubes alone are worth more than that!" (Heard at every swap meet. Gets me every time!)
Philcos: 90, 70, 71B, 610, 37-61 40-81, 46-420 Code 121 to name a few.
Plus enough Zeniths, Atwater Kents and others to trip over!
