Maybe it was owned by a stoggy parent...FM was pretty much classical and easy listening only till the 70's, AM was where the Rock was. It could have been sabotaged to avoid AM.
During WWII the government did something similar German families suspected of being Nazi sympathizers....Their radios SW bands were disabled by the government to prevent them listening to German radio transmissions.

That's interesting, I never would of thought of that. I was able to repair the dial lamp that was cut by taking some wire and splicing it in using solder and shrink tubing, unfortunately the dial pointer wasn't moving with the tuning knob for some reason so thought it might of been because someone restrung the tuning dial at one time or another and didn't do it correctly (didn't get the correct tension or wrapped the dial string around the tuning knob incorrectly so I thought I would try and restring the dial but I couldn't figure out the correct amount of times around the tuning knob pulley because like I said previously I couldn't find a service manual for this radio online anywhere for free download (nostalgia air didn't have it in their riders archive even though riders covered it) and Radio Museum didn't have it either (they didn't have the Sam's for it int their sams archive and they didn't have the Rider's in their Rider's Archive) and I don't want to pay $25 for the download at the Sam's website) and as a result of not knowing the correct restringing procedure for this radio I accidentally broke the tuning dial string which I now have to figure out what the length of the tuning dial string is that I need (which would of been in the service manual but since I can't find the service anywhere on line I'm kind of stuck trying to guess how much dial string I need because unfortunately I think whoever restrung this radio got too little dial string which might explain why the dial pointer had a hard time moving with the tuning knob).
I was wondering if there's any other websites other than Nostalgia Air or Radio Museum that would have my radio's service manual (either the Sams or the Riders).
