It's a BDY56 in disguise - but you don't want those!
Normal practice is to replace all of them with MJ15003's
Yes I know, and BUV20. But I would like to keep the original ones, though BDY56 and BDY58 are discontinued.
So MJ15003 is the way to go... how different do it sounds?
Still hoping to find a spare NA002 though, any help would be really appreciated.
You can be certain that those from China will be fakes.You can find "NoS" BDY56, BDY58 and BUV20 on ebay quite easily, but as to whether they really are what they claim to be, well that's another question entirely.

Blown NA002 output transistor, any chance to find a spare one?
A lot of transistors are made under license by various different manufacturers over extended periods of time. Provided it has the correct characteristics (ie meets the spec) and is properly licensed it's fine to sell it as the item described.
EG MJ15003 was originally made by Motorola but is now made exclusively by On Semiconductor.
Isn't this a quasi comp design, so the matching of outputs is unimportantCameron,
You might try calling LesW at Avondale Audio. He may be willing to supply suitable transistors and will probably match them as a pair for you. He might even have some Naim originals.
