Radio city products 664 schematic request
#1

Need a schematic or manual for the 664. The 663 may be similar.

Radio City Products Co. information is almost impossible to find, aside from advertisements in trade journals such as "Service." 664/663 service information is not found on any of several sites where I look for schematics and manuals. I did see a couple of booksellers listing copies of the 664/663 manual for sale at:
