Hello everyone,
The transformer in my KUBE broke down. Can't get a replacement from KEF. What I need to know is the output voltage from the transformer. It is KUBE 102 SP2088 if that helps anyone. Any help is much appricated.

Kindest regards,

Kjartan

Your mains transformer should say something like 2x18V a.c. @ ~150mA.

If you've dropped it, a winding to the coil has probably snapped, an easy fix if you can solder well and somehow get inside the case.

My Kube is 21V AC. I just bought a suitable transformer in a local electrical hobby shop and put it inside a wall wart...

One thing I was never clear on (I have a Kube 100): does 21VAC mean centre-tapped 21VAC (i.e. 21-0-21), or just simply 21-0 - just a single secondary winding. I got my Kube 100 from e-bay and it didn't come with a transformer; just want to know what the original unit is supposed to be.

I'm running my unit on a centre-tapped transformer (to get a full-wave output from the internal bridge-rectifier).


Cheers!

Hi everyone,
I've been trying to get a replacement for the KUBE 102 with no luck yet. Do you know of any internet site or a shop where I can purchase a replacement.

Thank you in advance,

Kjartan

These are no longer made. Sometimes EBay will have them at a price! Good luck.

Hi,
I made myself no clear with my last question. I need the transformer, not the whole KUBE. Do you know of any universal types that I can purchase and where I can get it.

I used a standard WallWart housing from Maplin.
Inside I installed a 9-0-9 Volt transformer tapping off at 18V.
That gave over 18V Off Load.
That then was wired to a DIN plug which was then plugged into the KEF KUBE.
Been working perfectly now for about three years...

Did the same for brother in law. That also is working just fine.
