What has made things better is an X-cap before the switch with bleeding 2M resistor. I chose it to be before the switch to save the switch from sparking.
But there is still some whining between stations, and the receprion is not as good, though I got a few stations.
Also, to align I need to put the dial back, and it is in rough shape plus a bulging paper on top the dial plate. I cut a slit in it, put some glue inside and left it between two pieces of wood in a vice overnight. I only need the dial for alignment; ot will be eventually replaced.
I also had trouble peaking the IF output from the 78 tube.
As I realized, the screw was stripped and they used two nuts to tighten it. I took the screw from the donor chassis, but it wouldn't peak until I soldered 30pF mica cap across the trimmer; then it peaked.
I never worked on a 38-14, so the challenges are new to me.
