I have two Musical Fidelity X-Ponents (X-Cans V2 and X-LPS) that are powered by 12v ac wallwart sockets. Both of these hum. Is there any replacement power supplies (Other than a second hand X-PSU for >£200:mad: )?
Cheers

i seem to recal that all it needs is a 12v transformer,you can get a 50va (4 amps) unit designed for low voltage lighting relitvly cheap,i belive lilolee done something simaler
 
Thanks for the offer Joolsburger - out of interest what are you using as a power supply now.
Do you think it's just that the MF WalWarts are c**p and if I try a few from other manufacturers I'll find a few that don't hum.
What I'm really looking for is a supply unit that will take a standard power lead with a IEC socket. Does anyone know if any exist.
Hippy - do youy think a halogen unit could be adapted - my X-Ponents are 12v ac 500mA.

Cheers all

yep, very simply id say.The transformers for halogen light fittings are normally rated at 4 amps,or more.one thing to check is that its a proper transformer,not an electronic transformer.something like this would do very nicley,you could even run both units of one transformner,theyd olny draw around 1A.
 
I use Trichord dino + upgrade thingy made a big difference maybe the thing to do is bite the bullet and buy the MF 200 quid jobbie.
 
Or get one of trichord thingys made for your M/f Kit, There is a guy called Pink Floyd, who makes up cheapo good PSU's for the M/F gear, they arn't bad either :) I use a derivetive of the N/C in all my gear, makes a very useful difference. WM
 
donut,
i think russ andrews does a 12v powerpak for use with a tivoli radio for about 40 ukp. i think it outputs dc though so it may not be what you need... it should be on his website.
cheers

Thank Julian - I had already considered these as they looked ideal until I contacted RA and they pointed out that they were DC :rolleyes:

WM - I have tried to contact "pink floyd" through his site but no response - also his site specifically states that he no longer builds these for people. That's a real shame as I think his own version of the PSU would have been ideal. Unfortunately my electronic DIY skills are next to none. I might however look into the halogen light option.

Hippy, regarding the halogen light transformer option - the only ones I can find are 50Va - I need 500Va - is this going to be a problem or won't it matter (as you can tell my electronics knowledge is near enough zero:rolleyes: )

Cheers all

Hippy - you're right - I've not got a clue:rolleyes:

The MF site states:-

Power requirement 12V AC 500mA (via mains adaptor supplied).

So I got things muddled.......
I'll have a go at this anyway.

I take it I can run both X-Ponents from the same Transformer and rely on the fuse in the Black Rhodium SuperMains6 Mains lead!

Cheers for your patient help :)

yep one 50va transformer will run 2 - 500ma devices easily.
The fuse in the mains plug will protect the cable and primary of the transformer ,the secondry winding (the 12v output side) is protected by a fuse built into the transformer.id be tempted to add 2 inline fuse holders,one for each x component on the 12v output of the transformer just in case.
