So, I was building a power supply for a 6111 subminy pedal. I have a 120-12v 750 transformer going into a rectifier. Then a 47ohm resister into a LM317. I adjusted the trimmer to get 6.3 v for the filament. Then I smelled something and the voltage dropped in half. Turns out the resister got very hot and burned out. Since then I changed out the resistor yet the voltage is still at half.
Any ideas would be greatly appreciated.
