SANSUI Output Transistors NMA/NMC 1012

Hi all

I desperately look for unfindable outout trannies the pair NMA1012 and NMC1012.
Only one pair is dead on my Sansui AU-919 and although I have replacement to change them all, I really really really want to get back to original ones ...

If you have by any chance such rare items, or heard where to get them (sure source) thanks to let me know
