I am restoring a Nak 480. The fasteners F9 and F11 are make of some cast and weak metal. One was not there the other broke. I am thing that nylon screws would work just as well. Any thoughts or warnings? Azimuth is controlled by a different set screw. Thanks Pepe.

The cast-formed screw I broke is F11 in this picture. The diagram is of the Nak 482 which has three heads and would require a second (F9) screw which mine does not need. This screw keeps the board on which the head is mounted pivoted and the angle controlled by the azimuth set screw. I was able to duplicate it using a tiny nylon screw and nut (source: Ace Hardware), so did not have to canibalize a second 480 I had. It was a useful lesson in RTFM first and dont freak out if a part looks weird, you may be able to achieve the same result with a regular fastener. I am listening to the 'fixed' deck now. Playing Celtic music - sounds excellent. Recordings made by itself sound even better (typical Nak). Recording in metal tape sound glorious, but who wants to mess with unobtanioum tape. [Side note - the RX-202 ad BX-125 I have for sale on Ebay have the strange quality compared to the others of making really good sound on cheap regular tapes - that was unexpected].
