Hard to find genuine Toshiba pre-driver transistor 2SC1628 - ONE PIECE.
Used in many Sansui receivers (such us G9000 or G8000) or amplifier (such us BA3000, AU20000). It doesnt has exact equivalent because it has legs layout Emitter - Base - Collector.
Modern (today) production of similar predriver transistors have legs layout Emitter - Collector - Base, so in some casese you can only use that genuine Toshiba transistor.
This what I am selling here, has hfe classification "O".
The price is for one piece.
