Thanks to Don Lind for his suggestions re- the ratio detector coil. I took it apart and found that the slugs were intact and did move up and down. I checked for an internal cap and there was one on the secondary only. It showed no capacitance whatsoever with the coil unsoldered. I cut it out of the circuit and carefully reassembled the can. I had no idea what value of cap to use in the secondary circuit. I dug into my stock of small mica caps and came up with a 47pf unit which I soldered in. I was now able to do a proper alignment and the secondary adjustment does not show a null. The radio now plays distortion free. Thanks again for everyone's suggestions.
