Atwater Kent 55F
#15

So far, not too impressed with AK.  the radio is up and running, but am having problems with the tuning caps.  The shafts for the movable gangs are worn and so will not stay centered between the stationary plates.  As a result, the 3 tuning caps do not track at all accross the dial and will not tune anything in on the lower end unless I physically push on the shaft to center the plates.  I presume the wear is a result of the side tension placed on the bearings by the belts that tie the 3 caps together.  Not sure what I'm going to do.  I'll dissassemble the caps to see if I can make new bushings to thighten things up a bit.

I haven't found any alignment instructions but it looks like the only way to adjust the 3 stages is to physically adjust the pulleys on each shaft for maximum signal.  Any ideas from experience would be appreciated!
