First off, I replaced every resistor that was out of tolerance.  But the transformer got excessively hot after a moment so I turned off the power.  I then proceeded to replace all of the remaining resistors, but the transformer continues to overheat.  Does anyone have some suggestions as to what might be the problem here?   I found none of the capacitors or electrolytics to be neither open nor shorted.

Thank you,

For the life of me, I cannot find the pilot lamp specifications on the schematic for the Nordmende Othello 53.  Does anyone know what this type if bulb is?  All I know is that it is a scew base type of lamp.

 

I also have the same question for the SNR Excelsior 52. Can someone help?

Thank you

Bob

I am restoring this same model with the Ortssender key and am seeking instructions for activation and use of this "short-distance transmitter". Does any member know if one of the 3 speakers (the center one) acts as the microphone for speech transmissions?
