The "new" model SL-x2 shown at the end of the prior thread was part of the expansion of the Module line, which included a base and dust cover. It differed from the SL-x only in name but allowed the introduction of an upgrade model in the series, built on the SL72B chassis but with the simpler-design tonearm of the 3500 and SL-x: the SL-x3, which had a Shure cartridge pre-installed in a dedicated mount:
SL-x3 wasn't that great a seller, as the higher-echelon buyer wanted more versatility, particularly in cartridge choice, which brought about the Model 74M previously discussed, with standard 1/2" cartridge mount.
The following two models are going afield from the ones above, whose tonearms were related. The next ones had tonearms far less advanced in design, and two-pole instead of four-pole induction or synchronous motors:
The expansion of the Module line also went the other way...downmarket. This model did not have a synchronous motor so it could not be called "SL" and was instead dubbed the X-10. It had a two-pole motor, a tonearm without weight counterbalancing; all the counterbalancing to proper tracking force was done by spring. It was sold with preinstalled ceramic cartridge, base and dust cover:
Further downmarket...but confusingly so because its model number was HIGHER than that of the X-10...was the Module X-11, a Garrard Demi minichanger with very simplified tonearm, and sold with ceramic cartridge, base and dust cover:
The low-cost Garrard Demi/X-11 would rear its cheap, ugly head later on, as Garrard used its mechanism to build a cheaper full-size line of record changers, the Unimech series, clumsy to use and feeling cheap, with clunking, balky controls; they were also very difficult and expensive to maintain, due to poor access to often-serviced parts. The Unimech was a cheapening of the Garrard line, an effort by its owner, Plessey to save on production costs, but which was the beginning of the sad decline of Garrard which would see it sold to a Brazilian company, as Plessey tried to recoup the losses it had itself created.
