"…I was more than a little surprised by the level of improvement it wrought from my system. You get substantially improved sound from your turntable and push button speed change to boot….for $159, you really can't go wrong. In fact, I would say it's one of the most cost effective improvements you can make to your system. If this little box works with your turntable, and you don't have an electronic speed control already, you are missing what your rig is truly capable of." – Adam Goldfine, Positive Feedback Online, Issue 31

Speed Box MKII Precision turntable power supply is a microprocessor driven supply designed specifically for Pro-Ject Audiophile Turntables utilizing A/C synchronous motors. The exact frequency and amplitude of output voltage is ensured through the use of a quartz oscillator coupled with an extremely low distortion amplifier to supply the turntable with a pure signal that could never be provided by using the standard wall plug adapter. The net result of this power supply is a very smooth and quiet motor providing a significant gain in audio performance.




Supplied with a 15" captive power cord for connection to turntable.

Placement is an Issue

In regards to the speed stability, the box seems to work fine. It keeps the platter turning at 33 1/3 RPM regardless of playing conditions. I noticed the box can induce a significant hum/buzzing into one's system, the loudness of which varies slightly, depending on its placement. In my system, the only way I could resolve this hum was to connect a bonding (ground) wire between the box and my receiver. Now the hum is completely gone. Note: the hum I am referring to is not the infamous a/c motor hum from the table, this box actually reduces that issue in the non-DC debut tables.


Does what it claims to do

If you play alot of 45s, this is handy device. As an owner of a Debut III, I previously found having to remove the platter & change the belt positioning to be rather cumbersome and time-consuming. This device also regulates the motor speed so there is a supposed sonic benefit, as well. A quick and easy installation, it replaces the power adapter included with the turntable. Take note that the cable that connects the device to the turntable is only about a foot long, so placement can be tricky depending upon your installation.


Great Product

Amazing how easy my life is now for switching back and forth between my 33 and 45 rpm records. The sound I believe have not changed that much. I think that's because I have a very good filtered outlet.

If you have a lot of 45's and is tired of lifting the plate and switch in the pulley... buy this product.
