This sounds like the best answer, use the original! Suppliers were all out
of the 39uf but we found some. Some answers were "it's related to screen
size", "runs cooler with the 39uf", "runs cooler with the 47uf", "capacitive
reactance is so close is shouldn't matter", "the 39uf is a upgrade", (that
one is in WinsTips).
Thanks guys, using original since we found some.

Looking at the serv manual and parts list there appears to be 2 very
close but different versions of that power supply. As well as C4108 ther
are a couple of other caps that are different and a couple of resistors
are different. Also the voltages on the IC and the SCR are different.
May be good judgement to use whatever the original was.
