pro-ject speed box 2 , all they say it is ?

i recently purchased a new pro-ject perspective 2 carbon. so far im really loving it. ive read a few reviews saying the speed box makes a great improvement to the sound of the pro-ject tables , though on paper i dont see how it would. ive got pretty clean power, i dont own any 45,s and i like a less cluttered system. and that little silver box would stick out like a sore thumb. but if a 120.00 gadget really does improve the sound that much ill do it. anybody thats tried it please advise, thanks

The Speedbox has a maximum output of around 3 watts I believe; the Lenco motor looks substantially larger than a typical 3 watt motor.

Lenco motor requires around 15-18W, IIRC. You are correct. Not to mention that if the Speedbox is designed for an AC synchronous motor, the Lenco motor is not of that ilk.

I have the speedbox 2 also and I notice a cleaner fuller sound but I think that comes from its ability to clean up the sine wave in the power so it has a good clean place to start. Since this thread is pretty old you have either decided to get one or you have decided against it. Bottom line, I love mine, seems like a lot of people like theirs. Question is, did you buy one and what do you think?

I just bought the pro-ject speed box 2 and running with my MMF 2.2 TT. I have a problem I am troubleshooting. I get a noticeable hum at 33-1/3 RPM that is not present at 45 RPM with 12" LPs. When I switch back to the MMF power supply there is no hum at either speed. The hum is only present when the TT is in motion at 33-1/3, and the stylus is in the groove. When I pick the tone arm up, the hum ceases. When I play a 45 RPM record, there is dead silence in silent passages - no hum.
I have a Shure V15VXMR cartridge on the turntable running through a Kenwood Eleven II solid state receiver. Polk LSI 15 speakers. Any ideas are appreciated. I really would like to make this speed box work to avoid changing belt around.

Thanks
