Anyone know where I can find one?
This is a plastic radio with a large tuning knob on the right, and a volume/on off knob on the left
The back cover, just said: Zenith Radio and has a Chssis 5NO3 followed by a 2-2273 it uses tubes 35W4, 12BE6, 12BA6 50C5 and 12AV6
A sticker on the bottom of the radio
shows:
model N508W
Z 384613 for serial number
I was hoping to find a schematic as the radio has a terrible Hum.
All the tubes light up.
Any ideas on the humm?
It was my grandpas radio and I inherited it.
Thanks Stephen

Hi Stephen,
Schematic & service date for your Zenith is in SAMS Photofact 817-11, which would date your radio around 1965 or 1966. The hum you describe is most likely due to leaky electrolytic filter capacitors, which should be replaced. Many public libraries have these Photofacts or can get them for you. Or you can buy a copy by calling 1-800-428-SAMS. There are also many online sellers of used Photofacts at much lower cost.
