See my attempt to combine the schematics into a more coherent form. No 
guarantees about accuracy, but several dozen sets of eyes have reviewed them, 
and I've made a few corrections. 

As near as I can tell, you CAN interchange the two versions of RF decks and 
power supplies. I own three of these amps, two of one version and one of the 
other. I have not run them "interchanged," but I've done that for testing and 
nothing has blown up and it ran. 

My website,  http://audiosystemsgroup.com/publish   has the schematics. They 
are pdf files.
