Actually, I thought about this for a few minutes, and the issue WAS
raised once, but it was a few weeks ago. There WAS a problem with GSE
equipment. According to Jim Lovell's book (No, Hedrick, I'm not going
to climb upstairs with my broken toe and get the page number; go buy
the book and read it!) until Apollo 10 NAA somehow "missed" the fact
that the systems they designed for 28 vdc in-flight were actually
receiving 65 vdc while hooked up to GSE during testing. That was the
reason the O2 tank was pulled from 10 and ultimately found its way to
13.
