[Amps] Central Electronics 600L

[RFlabnotes at aol.com]

I am trying to find some info on the RF transformers used in this unusual 
amp. Contrary to what I have heard, it was not a fully broadband amp. It has 
bandswitched  transformers for each band (80-10). But with a single 813 
running class B, how did they manage to get enough Q for harmonic suppression 
and still have enough BW to cover a ham band? I found the schematic on BAMA 
but it doesn't help. 

Can anyone help?
