So there is your problem! 62 should be connected + to pin 4 of the 84 tube. - connects to the junction of 61 and the green yellow wire from the power transformer. Replace 62 as it probably is damage from have the polarity reversed. Measure from chassis with the - lead from the meter and the + lead from meter going to the - side 61. Should read -10v or so and you'll have your grid bias back/ distortion gone.

figure out what all those squiggly meant.

Now I think I've got!
