The instructions for advancing the motor are for the 5-star soundhead. For the 4-star (SH-1000) the flywheel is shrouded and you manually advance the motor by turning a knob. --JesseCrooks (talk) 21:21, 6 May 2020 (PDT)

Replaced instructions to advance the mechanism by rotating the flywheel, which applies to the 5-star soundhead but not the 4-star (SH-1000) and other Simplex-compatible soundheads to the more general instruction to "manually advance the mechanism." Most projectionists will likely be using the SH-1000 or the 5-star soundhead, but they may have something else as well. Some earlier models could use an RCA soundhead. Not sure about XLs. --JesseCrooks (talk) 17:26, 7 May 2020 (PDT)

Add discussion of the evolution of the Simplex XL, Simplex 35, Simplex PR-1014. Pros and cons and differences between models (ex., poor castings on the XLs result in worse oil seepage). Also add discussion of Simplex soundheads. --JesseCrooks (talk) 21:26, 6 May 2020 (PDT)
