d998/b778 are in my jensen car amp and one channel is down, searched a little and seen some threads about this and i know the FJA4213 and the FJA4313 are best subtitute
but here's the question, can I replace D998 and B778 with 2SA1943 and 2SC5200?
or with 2SB817/2SD1047?
in replacing what spec is most important. voltages,hfe or...?
is it better to use higher wattage transistors?
wich pair's best?
