Rabco SL-8E Tone Arm

I owned a Rabco for some time. I set it up with a carbon fiber arm wand, and developed a servo for the motor that actually worked. It prevented the arm from lifting off prematurely, skipping and also got rid of the servo activation noise.

The servo was rather simple. I built it up on a little circuit board and hid it inside the motor/battery box. As long as the contact resistance was below 1 megohm it worked fine. That made the arm a *lot* easier to live with!

Nandric, I believe the "watchmaker" of whom you speak was Herb Papier, the eventual inventor of the Triplanar tonearm. I think Herb used to tell me of his adventures with the Rabco. The Rabco was invented and built here in the Washington, DC/Maryland area as well, by an engineer named Rabinow. (Hence the name of the tonearm.) Herb was a watchmaker by trade (or more likely a watch-repairer), before he got into the crazy business of hand-made tonearms.

Nandric: Yes, this is the same person. As Mosin said, David's one of the good guys. It's a privilege to know him.

Dear Lew, You are obviously in 'logical' trouble except if
Herb Papier had an alias : David Shreve.
I now recollect that the Rabco story started before 70is.
Back then my scholarship was $250 per month while the Rabco
price was the 'astronomical' $1000. I wanted then to know everything about this 'wonder' and think that I dreamed about owning one more than about any girl that I can remember. To get the 'right picture' think about your dreams about the sport cars in your student time.
The 'upgrade sickness' started direct after the introduction and I wanted to know everything about any of those while still dreaming about owning one. But my imaginary Rabco upgrade should be done by this American watchmaker who used ruby bearings for the purpose. I have read somewhere about this upgrade and was impressed with
the jewels which to my knowledge were only used in expensive Swiss watches. This was my association when Essential and Mosin mentioned David.

Regards,

Of course, that depends on how difficult it is to find the correct VTA for each. If you can find the "sweet spot", then all bets are off ;-)
