Radiola Guy's improvements to the Radiola 18 service manual
Component values added to the schematic that were never included in the RCA published schematics.
Dial stringing cable diagram that was omitted from the original published manual.
Hard cover, heavy paper, comb bound in the standard 8.5 x 11" format instead of the oddball 8.5 x 10" soft cover, thin paper original.
Enlarged fold-out schematic with filter choke values and notes.
