Jim!   the photo  I saw  had  the  unit in  a  standard  ksr  case.
remember  what  I  got  was  part   stuff...  and  I have   the  neutral 
20ma   card/transformer  that   would   go in the lesu so I  suspect  that is 
another  good indicator .. and  I have   the   prints  for it

Yeah,  the RCA Spectra was basically a copy of the IBM 360, with some
changes that  made it a better machine but prevented use of IBM's

It's very possible that the machine never had an LESU.  (L  for Model 28,
ESU for electrical service unit)  It's not an essential  part, just a
convenient place to put the line relay and its power supply  and some other
options.  So Xerox may very well have ordered the  machines without  LESUs.
