All of the other comments about the Rabco Arm..are true..It iis probably the....
SL-8 Rabco Arm.?..which I owned and used for several years..
It is a "bitch" to set up and to align cartridges with, but
we were willing to do that in those long ago days..But, if
you get this arm, it has a tendency to make a little "buzz"
as the servo engages to correct the arm geometry as it
traces the groove...that "buzz" sometimes would come through
the speakers as a little "zzz" "zzz" as the arm moved. It
was audible in quiet passages of music, but audible at other
times...Some arms were modified to eliminate that...M&K, I
believe, had one of the modifications available at the time
and arms which were sent to them for modification did not
buzz as they moved...Just a word of warning...Lots of fun
to set up if you enjoy this sort of thing, but patience is
required...Try to find the M&K Rabco if you can..There are
not many out there...the rest tend to buzz....
