Different animal. Bob kindly forwarded the schematics for the 3KA, which 
uses two 3-500Zs.

There are indeed a lot of things that could have been done differently - 
or rather, could be done differently now, in the light of 30 more years 
of shared experience.

It's a matter of philosophical choice, whether to make those 
improvements or to preserve a classic amp in its original condition.
