Hi all.
I have a Zenith K-731 AM/FM radio. Am wondering in what year it was introduced. Most antique radio sites say 1959-1960, but I recently had an email from another collector (in response to my request for a schematic, service info, etc.) in which he said the Sams Photofact for this model was dated 1963. Which is correct?
Personally, I'd say mine is from '63, given the absence of CD indicators on the AM dial scale (the Conelrad warning system was replaced by EBS in '63).
BTW: The Zenith Oracle site is currently offline due to being updated. I have no idea when it will be operational again.
