Re: Sony 2SD625 line output transistor
Interesting. The data I've got on 2sd625 gives its hfe as 120 which is on the low side for a darlington but high for a strait power transistor.
I have also already tried a high gain single transistor as a replacement. I used a KSC5027OTU. This functions to some extent, but not enough to produce a picture. It shows symptoms of lack of drive really. It also gets hot, which is reasonable if its not saturating when on.
I have the service data on this set but only from the radio and Television books. If you have a better service sheet for it I'd love a copy.
