Vestax PDX-2000 MK2 / 2300 MK2 Voltage Conversion - WA22AZ102-0 PCB
So you've bought a turntable from another country and you want to use it on a different voltage? You've come to the right place. Here is a step by step guide to show you how to convert your PDX-2000 MK2 / 2300 MK2 to a different voltage.
Not the right transformer? Check this guide instead.
You'll need the following:
- Soldering Iron - preferably temperature controlled
- Solder - I prefer 60/40 Tin Lead solder
- De-soldering tool - can be copper braid or a solder sucker
- Fuses - needed to adjust for voltage difference to protect your circuit
Here's a useful guide explaining about dual winding transformers, it's worth a read under the "Dual Primary & Dual Secondary Transformer" heading before continuing.
Be warned, you must be capable of working with electronics before attempting this. If you're unsure please ask a professional, we do not accept any liability for personal injury or damage to electronic equipment.
- Turn off and unplug the PDX from the wall. Unscrew the platter from the motor to avoid damaging it. Leave it for a while to allow the capacitors to discharge then place it upside down on a large bowl and remove the screws underneath to allow you access inside.
Inside you'll see the mains transformer, carefully remove the thermal fuse from the DC motor and unplug the two connectors on the left (AC In and AC Out)
You can now remove the screws which mount the transformer to the chassis. Be warned though the 4 nuts on the other side will drop out so you'll need to remove the platter and put the nuts somewhere safe.
- Unclip the connectors and with the transformer removed from the turntable chassis carefully inspect the markings on the PCB. You'll notice there are 3 markings denoting 100v, 120v, 230v. Connected to this board is a thermal fuse which acts as a jumper wire for the voltage configuration. J858 is where the voltage comes in, leave this alone. All we need to do is to change the position of the other thermal wire to the right voltage.
- As mentioned before, leave J858 alone, carefully de-solder the other blue wire from the thermal fuse from the PCB, it will be connected to either J859, J860 or J861. Do not tug and pull at it unless you are confident all the solder has been removed from the pad.
- This is the configuration for 230V operation, note how one end of the thermal fuse is connected to J858 and the other is connected to J861.
-
This is the configuration for 120V operation, note how one end of the thermal fuse is connected to J858 and the other is connected to J860.
- Re-attach back to the chassis taking care to ensure all screws and nuts are accounted for. Make sure that the tooth washer is connected to the same screw as the earth lug. Put the thermal fuse back in its holder near the DC motor.
- Since the voltage has now been changed on the unit we must also change 2x 20mm fuses on the main circuit board. It is imperative that you change these, don't try and cheap out by skipping this step. You'll either have a turntable which doesn't work or worst case scenario you have a potential fire-hazard in the even of a short.
Here's a reference table showing you which fuses you need when converting the voltages. It is imperative that you use the correct fuses below, if rated too low when converting from 230v to 100v / 120v and the fuse will constantly blow. If rated too high when converting from 100v / 120v to 230v and your circuit will fry and catch fire before the fuse blows.
Voltage Fuse F001 Fuse F003 100v + 120v 1A 500mA 230v 400mA T 315mA T
- Change the plug to your countries format, you will not require a safety ground (third pin) as the device is double insulated. Ensure that when wiring you connect the live and neutral wires to the correct connectors on your plug and you're good to go.
