The TD150 utilizes the same inner and outer platter system as the TD16x and TD14x series models. This means that drive pulley diameters will remain the same throught these model ranges.The earlier motors are 110 - 120 vac and will operate on either 50 or 60 hz power. Since the motors are of the 2-phase synchronous type, the motor rpm is governed by the frequency of the ac power at the wall socket. Motors that operate on 50 hz power will spin at a lower rpm than will a motor being fed 60 hz power. Consequently you need a different pulley diameter for each different power frequency.
Later mark II and those model versions that came after were supplied with a low voltage 16 - 18 vac motor that would use a 'converter' power supply that plugged into a wall socket. The proverbial wall wort. The Mk 1 and early Mk 2 TD16x and TD14x models came with the 110- 120 vac motor. Mk 1 tables operating in the UK and other countries that have 220 volt AC mains are wired to a resistor to drop the voltage down to 115 vac at the motor. This is accomplished inside the turntable cabinet at a mains terminal with a selection of connection options. The later low voltage motors would simply be supplied with the correct wall wort for the destination country.
To answer your question, will the TD160 motor work in a TD150?, the answer is yes. It will fit the mounting hole pattern too. What you need to know is which version of TD160 is this motor, the 110 volt or the later 16-18 volt versions. The motor in the picture you show looks like the earlier 110 volt motor to me, however these different versions of the TD16x and TD145x motors share a very similar outer casing. Be sure before you bid.Personally, I like the TD150 motor over the later TD16x and TD14x motors. It has less torque and should offer a smoother flow of power to the inner platter that it drives. The plastic clutch pulley of the later TD16x and TD14x motors is a multi-piece design that uses a compression spring to force a measured amount of pressure between a soft fibrous pad and the bottom surface of the pulley. When belt pull is great enough the clutch mechanism will slip. This is designed to reduce skidding between belt and pulley during start up. Personally, I don't think the lower torque TD150 motor really needs such a contraption. In favor of the clutch pulleys, they are owner replaceable so that wherever the table goes, the owner may replace the pulley with the correct size for the country of operation.
I like the look of the solid machined aluminum pulley of the TD150 motor. However, the TD150 pulley is intended to be a permanent fitment to its motor shaft. Perhaps this pulley could be removed from its mounting but not without a very specific and possibly dedicated hub pulling fixture. In practice, this means you will need to know which pulley diameter is attached to the replacement motor before you buy. The 50hz or the 60hz.
Hope some of this is useful.
