Hopefully this thread still has some life. After replacing the field coil with the resistor and installing a 4'' permanent magnet speaker, I was not happy with the cheap sound, so recently I changed to a 6'' speaker. The set picked up hum when I did that, so I had to increase the size of the second power cap from 4 uf to 16 uf before the hum left. I need to know if that is safe or not. Would the transformer get hotter? Seems to. Thanks !!!
