Good day to all, I have a Loewe Opta, Bella Rekord radio that has has an EL84 tube that gets very hot.

I'm aware that it's not unusual for this tube to be hot however the temperature measures over 100 degrees Celcius when measured with an infrared red temperature device.

The tube has burnt the insulation off the wires that are close to it and has heated the top cover directly above it of the radio enough to crackle and flake off the finish. See pictures.

I am in Canada and my line voltage to the radio is 122 volts. The radio does not have a transformer with different voltage taps (that I'm aware of) like the larger models.So I can't switch it to 127V.

Is the higher feed voltage the reason it's getting too hot or is it a component that needs to be changed or added?

 Pin 7 voltage is 265 v,  Pin 9 voltage is 240 v. The schematics show a voltage for pin9 208v and pin7 225v.

The radio is working OK but has a reverberation or distortion of the sound. Would the distortion be caused by the higher voltage to the tube or is it a separate issue?

I have not changed any components in the radio yet.

Thank you for sharing your knowledge and experience.

Best regards,

Vince Cappuccitti
