Spot the obvious design flaw in the Speedbox SE, yes the plug cable doesn't clear the bottom of the box, resulting in a wobbly speedbox. Solution is second pic!

I take it that the Speed box works ok with the Interspace Mike?

Yah. It spins the platter!

I think it improves the sound, not sure yet!

Might be something that I will look at if I decide to keep my Interspace, would be interested in your findings.

Will report back! The led display means I need one less lamp in my room.

I used to use a speedbox se with my Hyperspace. I found little, if any, improvement in the sound, but liked the convenient speed change and the standby switch.

When it broke down and was declared beyond repair, I decided, after hearing strong recommendations from folks whose opinions I respect, to build the "Meldano" PSU (Design and PCB by a poster named Daniel on DiYAudio - not sure if still available)

This is an amazing pice of kit that produces a really significant improvement in sound quality. It requires changing the motor for a 24V one (unless you want to build a transformer box) but very worthwhile. Fully programmable so you can set frequencies and phase shifts for perfect speeds and minimum motor noise.

I have the Speedbox hooked up to my Junior Spacedeck & IMHO it definitely improves on the sound for that model. Here in France it stabilizes the speed very accurately & there is an improvement in clarity which is noticeable.

Possibly it has less effect on the more senior models in the range, but it is interesting that the top Notts Analogue tables are supplied with a speed controller, so Tom must have thought it makes a difference when designing them.

Yes, they definitely can make a difference. My experience was that the speedbox didn't (to any meaningful extent - I don't believe in straining myself to hear small differences), the Meldano absolutely does, big style, and the Wave Mechanic might well do (never used one). I think Tom would have approved of the Meldano. It makes it possible to tune the motor for the lowest possible noise, very much in line with my understanding of his design philosophy.

Vinyl set up is beginning to sound awesome, not entirely sure its the speedbox, must be though, i'm hearing things I've never and I mean never heard before. Still not happy with the lean presentation of the passive pre, but i feel my system is very close to being 'there'. Big thanks to all the friendly advice on this forum.

In some respects your system is similar to mine, Mikeandvan. I have Junior Spacedeck (same platter as Spacedeck I believe), [Also Modified Lenco 75], Ace arm, Nag 200, Graham Slee Elevator, Slee Jazz club, Quad 66 pre, Quad 306 power into Kef 1042s.

As I said in previous post I have a definite improvement in sound quality with the Speed box so am not surprised you are hearing more good things.

Enjoy!

It is indeed similar. I love the Nag cart, I got mine from Japan, managed to avoid any customs costs, so it cost about £250, plus replacement styluses are only £100 direct from Japan. Great for someone clumsy like me.

I think I will keep an eye out for a speed box for my Interspace

Yes i'm pretty sure its working for me, I'll try listening with the TT plugged straight into mains to see the difference over the next few days.
