H/K - Rabco ST-8

Had one if these in mid 80s until about 2003. Tbh it sat after about 1990 unusec eventually banished to a damp basement. I did a quick refurb and sold it on eBay for $399 or so with a mid level, old Grado cartridge. I will never go back to vinyl (sound was fine but DO high maintenance and tonearm balancing, fragility, wtc. I was DO glad to switch to CDs and now streaming. 

However that black ST-8 was just about the most beautiful, coolest, piece of industrial design I have ever seen to this day. Even those recessed lights were one-of-a-kind. But was it any good? How would it sound now, all refurbed with a good cartridge? Why didn't linear tracking persist?
