This is the Day
Looks like a Helius Scorpio tonearm, had one on my PT1.YES! Well done you!! That is indeed the one, I always struggle to remember it's name. As I recall it was quite a nice TT, certainly a massive step up from the Technics (not hard I hear you all say), and in all honesty the Xerxes was better but it wasn't what I'd call seismic difference.
Found a pic, though I didn't have that arm on it (at least I'm still convinced it had an S shape silver thing)
Edited to add: I knew I wasn't going crazy, Linn did indeed make an S shaped arm:
Linn Basik LV-V:
Had that LV-V on my Ariston RD80SL, not the best arm but couldn’t afford anything better as a kid with just a Saturday job.
