is there a replacement for this part 2SA1302 or an upgrade that will work without changing other parts and what about the resistor R155,it is burned also,thanks
Which amplifier exactly are you trying to repair? How do you know the transistor is bad? Do you know if there are any other transistors that are blown? If you are trying to replace just one "burned" transtistor, you will also have to replace all parallel transistors as well.
it's a ms-275,i got this amp DOA someone has been inside ,the resistor had been removed and fuse f2 was blown,only one channel had some output but very distorted and kept going between on and overload,so i don't know if the transistor is bad or not ,i don't know if just the resistor burning up did this or the transistor went first,i'm not sure.
toshiba,2sa5200 coupled to a 2sc1943......the bi-polar trans setup..dont replace one without the other, beware of FAKE toshibas! u can get them on ebay for a couple of bucks, onsemi is a good brand as well as motorola
