staggeringly clever and well-engineered stuff.
I wish I could:
a) afford a properly fettled Nak. tape deck with full auto-azimuth adj. etc, etc.
and
b) that commercial small-format tapes were (properly) a thing again.
going by recent gear-acquisition and listening sessions to old pre-recordeds, I'd be done.
(btw, for anyone reading - the thing about 'baking' old pre-recorded tapes in a food dehydrator to get them to play ok (consequent material shedding during play notwithstanding) is a good 'thing' - it works, pretty much every time. Seems to be more effective than rehousing in a new shell - although doing both is recommended!)
