Vinyl Old timers: HK's and Rabco's

Need some help here. I have seen several old HK ( Harman Kardon ) TT's that had Rabco linear trackers on them. I always assumed that this was the Rabco 8 arm. I recently saw a Rabco 8 for sale on a website and it was completely different. The arms that i remembered looked like a regular linear tracking arm with a straight tube and a headshell. The 8 as displayed on this website looked like a much wider and flatter piece of metal i.e. almost like a piece of flat-stock.

If this really is a Rabco 8, what model arm is it that i recall as being stock on the old HK tables ? Sean

1. It would be very difficult, but not impossible, for an adept person to remove an arm from an ST-5,7 or 8 to install on another turntable since, on these, the main turntable motor drives the rotating armtube via an additional pulley on the main shaft of the platter.

2. The rubber drive wheel that engages the rotating arm tube can deteriorate or wear but it is replaceable by an "O"-ring used for plumbing. A ring with 3/8" i.d. and 19/32" o.d. is available and a perfect fit. I get them from Home Depot at 5 for 79cents.
