Value of a transistor at the amplifier sction
Transistors don't really have values, just a number on them. Most Japanese transistors are numbered with a letter first, A, B, C, K, and then a number. When searching for a replacement you add the this at the start "2S" so 2SB500 for one marked B500. If you can't read a number due to damage, with stereo amps the two channels are the same. So if the left channel transistor has burnt up look at the right channel one, you will quickly see the parts around it will be arranged the same as the blown channel.
