for Jean Hiraga 20W amplifier.
is there any difference between 2SD188 and NEC D 188 ? I need to replace one pair of 2SD188/2SA627. I got one D188 in place of 2SD188.
thanks
Pat

manufacturers will often mark their components without the "2S" prefix. if your tests indicate no problems, go for it. is that 500 ohm pot used to balance the output bias to "0"?
