David Rucklidge asked, "On the lid is a label referring to the type of motor used in this unit 'frequency generator DC servo;' is this the same motor as referred to, earlier on in this thread?"

The "frequency generator DC servo" label on the dust cover refers to the type of speed regulator on the direct drive DD models. The label on some direct drive models, however, was "Direct Drive."

My GT-35, GT-25 and GT-35P have both a DIN socket and phono jacks, with a connection for a removable ground wire. This was changed in the -1 models.

Otherwise the -1 series of GT- and DD- models was mostly a cosmetic update to the corresponding earlier single-play models, while the record changer models GT-25 and GT-35 were not updated to -1, probably because their sales had been weak and there were substantial remaining unsold stock. On the -1 models, the all-black counterweight that was introduced partway through production of the earlier series became universal (black paint was cheaper than chrome plating). The plinth was simplified and the moulding of the plastic lower plinth was changed to present a lower-profile appearance, though the actual height was virtually unchanged. The option of a plinth with its top in woodgrain instead of silver was offered. The only functional change occurred on the late-production version of the GT-35P-1, where the dual fine speed adjust knobs for 33 and 45 speeds were replaced by a single speed adjust knob.
