Hi.Radiophiles, It came to me for repair/recover one portable radio LX 437 AB.I don't have its schematic,but supose  may be similar to model LI 437/AB.My problem is that I don't have the correct filament tensions when switched to the mains.As a matter of fact,the wires that should conect to the batteries have been cut so I can not test it with the batteries once they are not there.And some help would be very welcome if somebody could explain me the wiring of the tubes filaments,once I find very dificult to understand the complexity of the switch wiring together with the dificult access to components and lack of data of voltages.

May I wish to all members and their families a Merry Christmas and a Happy new Year with greetings from our Sunny Algarve!
