You know you can replace each audio transformer with 2 resistors and a capacitor.... disconnect the old transformers and place a 10K ohm resistor in circuit between the points the plate winding of the audio transformer once connected, take a 1-2M ohm resistor and connect it across the points the grid winding once connected, now connect the plate lead to the grid of the next tube with a .1uF capacitor, rinse and repeat for the other bad audio transformer.....I can draw you a schematic later if you would like.

Thanks, I didn't know that. That's a simple solution, for sure - "capacitor coupling" the stages instead of a transformer? Is that the correct terminology for the circuit?
