The RM schematic is the 38-15 schematic.

I don't recall ever seeing a 38-17 schematic or service bulletin. As you stated, the 38-15 is basically the same.

You will find better info here, and higher resolution, than that found at RM - and you don't have to pay for it, either.

The same change in the 2nd detector circuit you described was also made to later production models of the 38-15. That change is described on page 22 of the Philco Changes in Models document, which you may download here:
