Hello all, I have a Revox B77 MKII. On the rear sticker it states 2 track
NAB, however I do not have any NAB adaptors and the machine is fitted with
the normal spring loaded clips for reel attachment.

I don't understand why the machine is labelled as NAB, as I thought this
was
a reversible option depending on adaptors fitted.

The machine is high speed (7 / 15)

Can anybody shed some light on this?

Thanks

Hi Oddjob

this may be referring to the equalisation used for recording - there are two
major ones - IEC and NAB.

Cheers, Mike



Yes that's what its referring to. The NAB big hole reels are catered for
by NAB adapters.

Wasn't they called NARTB once?...
