I have the same model radio (Zenith 6S229), purchased the exact same way (last minute impulse while leaving Kutztown -- exactly five years later than OP), with the exact same problem.  I have never replaced or repaired a band, on a Zenith or any other vintage radio; could you explain the process in greater detail?  the radio works fine otherwise, and I can even tune it by reaching inside and moving the bread slicer manually (I know, bad idea -- but it works). 

Thanks.
