Offered here is Volume XI of John F. Rider's Perpetual Trouble Shooter's Manual, published by John F. Rider Publisher, Inc., New York City. This massive reference volume is packed with radio service data, chassis schematics, alignment instructions, and troubleshooting notes covering dozens of manufacturers and models from the era — a cornerstone reference for vintage radio collectors and restorers.

Condition: This is a well-used working reference copy, sold as-is. Please note the spine has damage at the top hinge — the cloth spine has separated/cracked from the boards with some fraying at that joint (see photos). The text block itself is intact and solid, with clean, legible pages throughout. This is a very heavy book (9 lb 7 oz), so please factor that into your expectations for handling wear on a book this size and age.

Please review all photos closely, including the spine damage shown, as they are part of the description. Sold as pictured.

Shipping: Ships via USPS Media Mail.  Packed carefully to protect the spine and corners.

I have several different volumes from this series listed - check my seller's list - I also have a fantastic 1937 Crosley Radio Display Sales Book that anyone interested in antique/vintage radios should look at.
