OK, thank you Lawrence. You're right, with the AM selected I have voltage in the pin8 of ECH81.

I rechecked the voltages in all the tubes and I detected no voltage in pin8 of EF89. I checked the resistors nearby and I found R12 (100kohm) in open circuit... I replaced it and the set is now playing.

I will reassemble it and let you know the final result.

Thank you so much Jim and Lawrence for your help.

Kind regards,
Diniz from Portugal
