Custom Power Supply for 6v DC Motor

Hi Hicham. Whether the effort is worth it or not depends on how happy you are with what you had before. I hope you'll have a chance to post your results.

My own experience with aftermarket regulated supplies is limited to my Apogee Mini-DAC. I had originally replaced the stock OEM switching PS with a SLA battery but was having trouble remembering to switch off. I sent 2 batteries to recycling and then found an appropriate supply on eBay. My impression is it works as well as the battery.

Tobias, this little project will be completed by the end of March.

It is about a one single Power supply Box delivering regulated linear DC to 3 different components (DAC, TT motor. and a Phono Preamp) as per the following requirenments:

DC 12 volt, 0.75 Amp
DC 12 volt, 0.4 Amp
DC 9 volt, 1 Amp

No, the Amazon Model 2 is just a wall wart connected to the motor. There is an adjustment screw for each speed but no external controller for this model. I've spoken to a couple of owners who have found external supplies that have improved the sound. Unfortunately the companies no longer make them in the correct voltage. I'm going to take a look at the medical supplies out there.

If there are voltage swings in my AC, is a robust power supply (such as the one's offered through Acopian) likely to help my turntable's DC motor keep it's speed?
