Difference between Manley Compact 100 and Compact 80 amplifiers? Problems?


Hi guys.  I am becoming interested in Manley monoblock amplifiers.  Can anyone tell me the difference between the Compact 100's and the Compact 80's.  They seem to have the same circuitry and tubes?  Was this just a name change because Stereophile raised questions about the design of the Compact 100's (which came first, when there was no Compact 80's in the line.)  Were some of Stereophiles objections met by a bias redesign with the result of a downgrade in power?  Any help would be appreciated.

Also, I am nervous because my preamp is an ARC SP-6a, which did not have auto-delay relays before letting the preamp stabilize, and I suspect that this would sooner or later give rise to the condition that S-phile says would blow the amps up?  Any negative experiences out there with an ARC SP-6 or 6a and these Manley Compacts?

Some of those transformers are hard to source.  VTL service and support were horrible in my experience.... they hate servicing legacy products that are bought used.  I learned the hard way with a used Compact 50 , which sounded great when it worked.   Most unreliable, I should say ONLY unreliable component I’ve ever owned and I have owned many.
