Original vintage SAMS Photofact Folder 423/9, not a disappointing inferior quality copy.

30 watt audio amp.

Mint new condition, never used, spine nice and tight fold.

Paper slightly toned, straight edges, square corners.

No writing, no notes in any of my SAMS, they are new old stock.

4 pages of schematic, parts list/locator, alignment info,....

Shipped flat in manila envelope with stiffener to help keep flat, not folded up for smaller envelope.

I usually ship the next day.
