musical fidelity x-ray v8 - psu spec ?

fatgaz · 26th June 2008, 03:41 PM

Hi,

musical fidelity have an odd cd player called the x-ray V8, which does not come with a PSU - it takes it's power from an external unit that powers an integrated amp or it takes power from a DAC.

there is no info on the Musical fidelity web site/ manuals as to the actuall PSU requirements of the CD player.

does anyone know what this player needs ?

there seems to be a '5-pin' socket that is used.

I may be able to buy just the cd-player and so I may need to build a PSU for it.

anyone got any ideas - or do they have one of the PSU's they could measure ?

cheers all,

Gareth.

Hi,

just asked MF for the spec of the PSU and the guy clammed up saying - can't tell you anythiing about modifiying our products...

but he did start to say it's +/-15V ac and +/-9V ac

so i'm getting somewhere !

just need to know the input socket wiring pinout and the required current capacity and I'll be able to knock up a box with two transformers easily.

so - can anyone measure the output (that can feed the cd player) from either X-serise PSU - these feed the amp or tuner - OR from the x-dac ?

cheers !

Gareth.

Protectionism in the industry ? No never. (sarcasm)

sorry I can't help as I don't have that model, but maybe open the cd player and see if there are any markings on the board.

Hi all,

some one on another forum has measured the output from the dac that feeds the cd player - seems to be two phases each of 5V ac and 15v ac. so they have just taken the mains transformers outside of the player.

I guess that the 5V will run the mechanical/ display side and the 15V will be audio rails ? not sure where the dac will get power, probably the 5v ?

thus, i'm going to have to guess on the required size of transformer - obviously the current draw won't be enormous - but I don;t want to blow too much money on unnecessary iron.

any sugestions on the transformer sizes i chould use ?

thanks,

G.

I would hazard a gess that 1 amp should be plenty.
But at these sizes, I doubt they'd be expensive so maybe look at 2 or 3 amps.
