Assorted Harman Kardon RABCO tracking wheels. Various sizes, the smallest ones are from an unknown deck, possibly an SL series or an ST-4. I got these parts along with many other Harmon Kardon Rabco parts, including those from ST-5/ST-8. As best as I can tell, there are wheels from the ST-7 class (grooved for a rubber tire), and from the ST-5/ST-8 class (solid metal). I am offering these in case someone needs any of these parts. Any questions, please, please ask. And, if you know better than I do, please let me know.

Two Harman Kardon Rabco ST-5 ST7 ST-8 Tone Arms/Wands. One of them is missing the tracking force adjustment weight, it has a 3d replacement T-Bar, work great. Narrow head-shell. The other has two of the cartridge connectors twisted off, on is lost, one is included.. It has the wider head-shell. The screw holding the head shell in place is not original, but holds in the T-Bar. This is how I received it. See pictures for details. Please, please, ask any questions. From timothybhewittesq: FYI - These are not for an ST-8 Response: Hi timothybhewittesq,I respectfully disagree; the wands from the ST-5/ST-7 are electrically and mechanically interchangable with those from the ST-8, and vice-versa.There is a single difference, the knurled Lock Nut ,Tone Arm is silver on the ST-5 and ST-7 with straight cut knurls, and black on the ST-8, with a crosshatch knurl. But they are otherwise identical, and as I stated, interchangeable.So I stand by the statement ST-5, ST-7 ST-8 Tone Arms. (emended the description to use the phrase Tone Arms instead of Tonearms, in keeping with the official Harman Kardon documentation parts description.And, as always in my life, I reserve the right be be proven wrong!Best, H
