Help identifying component

Hi!



I'm repairing a PM 710 DC Marantz Amplifier



Fault from the output transistor. the only mark is NEC C 2588



does anyone know this part and can tell me what to replace with ?



Thanks

Maybe 2SC2588?

Specs according to my old "Towers International Transistor Selector":

NPN special package L34 pinout (BCE) Vcb=150V Vce= ? Veb=5V Ic=12A Tj=150C Ptot=120W in free air ftmin=30MHz Cob=170pF hfe=150 typical hfe_bias=2A use=AHH (audio, high current, high voltage) manf=NIP (NEC) EUR equiv= ? USA equiv= ?

NTE used to have an equivalent, NTE33:

TB-34 case, 15A, Vcb=160V, Vce=160V, Veb=5V, hfe=120 min, Pd = 150W, fT=80MHz

Rockby in Australia have one left at AU$40 (~US$30).

FYI, NTE34 is the PNP complement to the NTE33.
