Vintage "Perpetual Trouble Shooter's Manual, Volume VII" by John F. Rider, published by John F. Rider, 1440 Broadway, New York City. This copy features the Sylvania Radio Tubes co-branded cover — Sylvania (Hygrade Sylvania Corporation) arranged for their name and logo alongside the standard title, a nice detail for tube-brand collectors as well as radio service reference collectors. This is the classic radio service reference used by technicians for troubleshooting vacuum tube radios, covering full circuit schematics, service notes, and parts lists for a wide range of manufacturers, along with Silvertone, Washingtone, Kolster, G.E., Crosley, and other model-specific service change notes.

Also included is a separate softcover "Sylvania Set-Tested Radio Tubes: Average Characteristics" reference booklet from the Sylvania Radio Tube Division, Hygrade Sylvania Corporation (Emporium, PA / Salem, MA), housed alongside the main volume.

Heavy hardcover volume, weighs approximately 9 lbs 3.1 oz. Black textured cover with silver-stamped title, "Volume VII," Sylvania branding, and radio tower/lightning bolt graphics on front and spine. Shows honest age and heavy use: page edges dry and worn along the fore-edge with some torn/repaired pages, cover corners and spine ends worn. Text pages and schematics inside remain legible and intact. A substantial reference piece for radio collectors, restorers, or antique electronics enthusiasts.

Sold as-is given its age and condition — please review all photos closely before bidding.
