Naim n-SUB’s amplifier & drive unit?

When I spoke (some years ago) to Naim about mine, it was made clear that although based on the NAP250 power amp, being not fully regulated and not quite a 250, it did NOT require the same service intervals as an old 250.

One of mine is sitting by me in that state just at the moment!

I discovered one morning that it was powered off. Subsequently found it was immediately popping fuses!
I had to change the bridge rectifier……

I had a look around, just out of interest, and discovered it uses Naim NA-007 power transistors, which were originally designed for the NAP500, I believe?

(Just an interesting (to me) observation!)
