There are specialists who work only on these, including one here in Australia, who always seems to have a few for sale on Ebay. It has its weaknesses, but was a nice attempt to eliminate tracking error by keeping the cartridge tangential to the record groove at all times. The most interesting part is the tonearm. Like most Garrard changers, cleaning and lubrication needs to be done to keep them working well.
I was interested in these for a while when I got into hi-fi back in the 70’s.
