Hello. This is my first post on this forum, so I should introduce myself. I have a quite large collection of LPs, principally of classical music, and over the years have accumulated an assortment of turntables, tonearms, cartridges, valve preamps amps, and speaker systems. I suppose that by this time most of this equipment may be considered to be "vintage", since its all from the 60's and 70's. Among my turntables are the Garrard 301 and 401 and the Thorens TD124, 125, 160, and 166. Recently, I moved from France to Brazil. In terms of electricity, that means I've gone from 220V/50HZ to 127V/60HZ. Thus, my question about the Thorens TD124 MKII, which I like to use in my main system, coupled with the Ortofon RMG 212 arm.
Although the machines are excellent, the Thorens manuals are far from models of clarity. The TD124 manual contains only a few lines in regard to adjusting the voltage setting. Since the line voltage here measures 127VAC, I moved the screw in the commutator to the "125-150 position. For line frequency, the manual claims that the table can be adapted for either 50HZ or 60HZ use, stating only that "... adjustment to the frequency of the power supply is made by reversing the motor pulley ...". It provides illustrations of the motor pulley in the 50HZ and 60HZ positions. Apparently, I need to remove two screws from the pulley in order to flip it over to the desired position. It also states, without further clarification: "IMPORTANT NOTICE. The motor pulley has been dynamically balanced to very close tolerances at the factory. When reassembling it, first tighten the black screw, and then the nickle plated one". Fine. I removed the screws. But the pulley doesn't budge. Removing the screws seems to make no difference at all. I don't want to force or pry anything, because in so doing I fear that I might damage the motor shaft. Its stuck. I'm stuck. I hope that some much more experienced forum member can provide guidance.
