Greetings to all
I have an amplifier using a STK4192II IC. It seems that a number of manufacturers have used this same IC in their amps.
There are 2 burnt/blown resistors in the power supply section which I want to replace, but obviously their markings are no longer visible.
I measured them out of the circuit and one was open circuit while the other read 5.3 ohms. They seem to be identical resistors (unsure) as they both appear to to follow similar paths to the chip: from power supply capacitor bank to two unmarked caps, to the resistors in question, to the fuses, to the chip via a couple of other component (caps and resistors).
I have attached pics of the circuit board as well as pics of some (identical?) amps.
Does anyone have a similar amp and can tell me what the values of these resistors are please? Or anyone have an idea of what they are?
Thanks
Max
