New here, an 89B I'm repairing
#13

Hi and Welcome!
I would add a few more turns to the winding you fixed on the osc coil. Methinks you don't have enough positive regeneration (feedback) Jon's set the 19 uses a higher gain tube so it doesn't take as many turns. I'd try 4 more turns should do it. Two important notes: When you rewound it it MUST be wound in the in the same direction. If add the 4 turns and just improves the tuning but still won't the whole band add a few more turns.
