    Need advice on Harman Kardon ST-7 / ST-8 turntable motor wiring

    HK RABCO ST-7 Tracking Roller Questions

    I have two ST-7 Turntables and may have made a mistake. I removed the Tracking Rollers from both of them to realize the rollers are not symmetrical. Upon measuring them I discovered one side (axel) is longer than the other. One axel measures approx. 6.6 mm and the other axel 6.8 mm, so there's...

    Harman Kardon RABCO ST-7 Source for Replacement Belts

    I've recently purchased a Harman Kardon RABCO ST-7 and am looking to replace the belts. Are they both the same? If not, any suggestions for a good reliable vendor to purchase these from and know I'll get the correct size belts. I've purchased belts for other turntables and found that if I didn't...

    Harman Kardon ST-7 strobe issue

    Hi All, So I just dove into my first ST-7, replaced tracking wheel, belts, DeOxit on pots, etc... After much frustration, cussing, cajoling and downright threatening (it never seemed to listen at all, btw) it’s up and running and sounding great. My issue is that the strobe speed is off. When...

    I love my Harman Kardon Rabco ST-8, But....

    I really like the HK Rabcos. I think they are a really clever mechnical design. I like how the travel of the tonearm carriage is directly linked to the rotation of the platter, so they are alway in sync. Really smart. Here comes the but....After years of using my ST-8 on my secondary system...

    Harman Kardon ST-5 Rabco Won't Track

    After seeing a little discussion here on the H/K Rabcos, I decided to get back to my disaster ST-5. It is in shambles. I am having a frustrating problem with it. Everything "looks" good, but the darn thing tracks slow, in other words the arm leads the carriage. No matter where I set the...
