hope you boys are doing well - so after rewinding the oscillator several times with (still) no apparent oscillation afterwards I noticed another issue that I thought was related.  The volume would not adjust at all or when it did a crackling sound accompanied the radio. I them resorted to substituting all tubes and cleaning the prongs.  Still same issue. today after troubleshooting again I happened to stick my finger into the IF adjustment screw and noticed that pressing in certain positions  would completely eliminate the crackling and restore the volume control so apparently the calibrator screw is shorting out ...does anyone know if these can be restored or should I look for a replacement on eBay? I am so relieved that almost 1 year after my original posting I finally figured out what the H**l was going on... Thanks fellas
