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.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
