Zenith L600 User Manual
This instruction book is for the Zenith Model L600 chassis 6L40 Super De-Luxe Trans-oceanic portable valve radio. This book is usually found inside the radio affixed to the back panel and contains user instructions, service notes, and circuit diagram. Since this is a valve radio, the heat usually damages the paper causing it to yellow and warp. They can also be destroyed if the dry battery pack leaks.
