My first impressions when I saw the NS7150 was what a smart, modern looking design it was. Compared against its natural competitor, and the machine it replaced in my system back then, the Akai 4000D it looked positively space age.

Build quality is not as substantial as the Akai, the plastic case is quite lightweight, however I would argue that it is good enough given that it is equipped with a full logic control system as opposed to clunky levers that require a sturdy base for satisfactory operation.
Unfortunately the use of plastic for the transport/pinch wheel assembly means that these can fracture over time, I have been very lucky, probably because I used mine regularly and kept it well maintained.

In use it is a delight, the controls are well laid out and work with a Nakamichi feel, very surprising at this price level. Fast spooling is quiet and results in a nice tidy spool on the take up reel, something the Akai could never quite manage.

Having pulled it out of storage I am amazed to discover that not only does it still work, it still works perfectly, the only issue being the on off switch which had jammed. A few squirts of GT85 freed it up but it then wouldn't lock 'on'.
I resolved the problem by flicking the switch violently with my thumbnail to see if it might engage the pawl, on the umpteenth attempt it worked and I shall in future use the plug as the on / off switch.

I have a Toshiba ADRES unit and a Videosonic Dolby unit which are useful at 1 7/8 ps, but which are not needed at the two higher speeds. Speeds are all stable with improvements in speed stability coming with the faster speeds. IMHO at 1 7/8 ps with noise reduction it will equal or better most cassette decks running metal tape.
At 3 3/4 ps it will rival a Nakamichi, and at top speed if you want better you will probably want a Revox.

I hope this may be of use to someone in the future.

re: N7150

Hi reel to reel fans , does anybody know a fix for the pinch roller mechanism on this N7150 and the bigger N7300 ? I have both this one has failed, the usual little flimsy lug has snapped off but the N7300 still works for now !! Also how do you remove the left hand reel table to change the counter belt , I know there is a fixing in the black plastic height adjuster but I just cant see what it is and how its removed .Thanks Gordon.
