Marantz 2130 Specs

I wasn't sure if I could believe any online specs.  Ben Blish is a 70's marantz proseletyzer.  Lots of people may crib there numbers from him.  I thought it was very suspicious that Marantz did not include any performance specifications in the owner's manual.  Lots of technohype, no specs.

But I did find specs in the Marantz Service Manual.  I believe those are official.  And they are superb.  They are clearly better than the specs of the Kenwood TX-8300 even in the RF area.  That doesn't seem believable.  The TX-8300 uses a much larger 6 gang capacitor, and of course it has a serious reputation.  The 2130 didn't have much reputation, possibly undersevedly so, until Ben Blish or one of his predecessors started bragging about 70's Marantz.

So, do I believe the Marantz specs?  I don't know.  I think there's room for doubt.  Anyway, lets compare the specs of Marantz 2130 to Kenwood KT-8300 by their numbers:
