Ok! I have tried with 90vac and rectifier on place, switch on and nothing made smoke checking the tubes all filaments are normal, 5Y4 is hot but less than first try and now I can see a small glow in what I think are the filaments in both sides of the black "shields" inside the glass(first try nothing), checked the voltage in #56 and is arround 250vdc, the schematics say something arround 330vdc I will try later to go full voltage and I will tell here the results. Thanks again for the help to get back to life this radio!
