    I wonder if someone can help me out. I am just getting back into the electronics world and need a little help. I am working on a Soundstream car audio amplifier and found the output transistors burnt out on it. The numbers are D718 and B688 which I take to be 2SD718 and 2SB688. They are Toshiba 120V 8A 80W SC-65 type transistors and I am looking for either original parts or a substitute number which will perform the same. I have been given NTE36/37 and FJA4213/4313. Both seem a little different. Anybody have any suggestions. I live in SW Ontario if anybody knows where I can get these little gems. Thank you in advance
