Looking for a datasheet on transistors NEC 2SD388A and NEC 2SB541A
I am unable to find a datasheet for the transistors NEC 2SD388A and NEC 2SB541A. I have found some transistors that will work for them as per an audio thread from a couple of years ago but I have no idea which of these old transistors is a PNP or NPN so I can replace them correctly. Any ideas? I am fairly new to vintage audio but I have some general knowledge of electronics.
