im fixing my friends old audison amp, and am having problems finding the original part for the transistors in the output section.
the originals are STmicro BDW93/94c and i cant find them, the only thing i can find is the STmicro BD911/912 pair.
the volt/amp ratings are ok, but the:
---------------------------------------------------
hfe @ Ic Vce min/max are totally different.
BD= min-15.....max-150.......(A)5...(V)4
BDW=min-750...max-20000...(A)5...(V)3
---------------------------------------------------
Vce(sat)@Ic Ib are also different
BD= (V)1 ....(A) 5....(ma)500
BDW=(V)2......(A)5....(ma)20
--------------------------------------------------
will the BD work? what exactly is hfe and Vce?
thanx
