Re: Help diagnosing Pyle Receiver PTA66BT with burned resistors
So this is odd. I confirmed chips F and G and the CD IC are disconnected and drawing no power
So right now V- has chips A-E connected, and nothing else. It has 6.14v across the resistor
V+ has chips A-E connected, and the power LED. It has 6.2v across the resistor
Why is V+ resistor getting so much hotter than V- with such a minimal load difference? Do metal oxide resitors just run that much hotter than carbon film ones? Or is something else cause that V+ resistor to overheat? It can't be any missing connection or load or else we would see that in the voltage reading, correct?
