I need some help identifying a transistor(s) on the main board from a Paradigm subwoofer. I’ve contacted the manufacturer and they have no answers as they longer have parts for this sub. So I’m left to identify them myself.
I’ve included a picture of the outward facing transistor’s numbering. The 2 brown transistors in the picture are identical in colour, shape and size. They appear to be BJT’s but I’m not sure. And their numbering is different. I assume that is significant. The numbering for the 2 transistors is as follows,
I assume the ECB simply identifies the pins and can be ignored to identify the part.
Any help to narrow this part down would be greatly appreciated.
