I have repaired a 70's vintage hi-fi tuner/amplifier that looked as if
lightning had hit the speaker wires, a Tandberg Huldra 10. The finals are
MJE2955/MJE3055, the drivers MPSU06/MPSU56, and the pre-driver stage an
SPS5384 (Motorola?).
I have found exact replacements for the finals, and replaced the drivers
with TIP31C/TIP32C.
I could not find any data for the SPS5384, so I replaced it with a TIP31C
which is NPN and can take 100 Volts. I find now that the amplifier is more
noisy with the volume control set low than it should be. I am assuming that
this comes from the pre-driver stage.
My question is if anyone know any data for the SPS5384, and can suggest
replacements.
Thanks,
Sverre
