It does what it says on the can, it filters and conditions the incoming power from the national grid into a cleaner power supply which supposedly improves your hifi sonics. There is a difference between mains conditioners and regenerators. I use a regenerator (the PS Audio P10) to good effect. Some claim mains conditioners suck out the life in music, so be careful. The speed box will not work on the Garrard it dosen't have enough voltage for the Garrard motor.
    Ok thanks, so I need to look for a regenerator, the Speedbox I can use on my Notts analogue TT, see if it makes a difference. So what does a dedicated TT power supply do that is different from just using a wall socket?

    Mike, I think you need to maybe have a look at the PS Audio and Isotek websites. You will find lots of advice, downloads, articles etc which should answer all your questions. But I'll answer your last question. Incoming wall socket power supply is basically full of crap. Power supply instability will generate (albeit minor) fluctuations in the spinning speed of your 401's idler wheel and therefore platter. You will notice pitch instability, piano music being a good example. A decent clean, stable power supply enables your 401's idler wheel to spin with less fluctuations and hopefully improved pitch stability. Hope this helps!

    Have a read on Lenco Heaven about Nigel's Speed Controller. I built one and it made a very worthwhile improvement to my replinthed L75 and works well with Garrards apparently although I believe it stops the strobe light from working.

    Well, the strobe still lights up, it just doesn't operate at the correct frequency.

    But this problem can be solved as well... For a price...

    Thanks Andrew, yeh sort of helps, so a TT power supply is just a mains conditioner? Like you say just buy a mains conditioner or regenerator for the whole system. I always thought that what TT power supplies did was specific to turntables, but it seems not. Think I'll keep an eye out for a mains regenerator then, just missed one on here that was the same price as the Pro-ject speedbox I just bought!

    It doesn't stop the strobe light from working, but the strobe markings are calibrated for a 50Hz supply (UK) and if you adjust the speed from the controller then you change the frequency of the supply to the 401. There is nothing to stop you from setting the controller output to 50Hz and selecting speed as normal on the 401 if you want.
