rebuild a Musical Fidelity X-10D ??

Is it possible to rebuild a Musical Fidelity X-10D into an Phono MM pre riaa??

Shoog · 27th August 2006, 06:59 PM

Basically No !

The X10D is a unity gain buffer using a pair of ECC88's. For a Phono preamp you would need much more gain than availble from a ECC88 alone, you would also need to fundamentally design a new circuit - which I would guess you couldn't do yourself. Also the X10D works at a sub-optimum voltage which would make it nearly impossible to drag enough gain out of it.

There are plenty of excellent and simple phono preamp circuits about, don't destroy the excellent X10D to make a crap one.

Hope that helps.

Thanx your answer is verry helpful. I'm not going to mod., will look for new phono amp..

Do you still have the schematic of X10D ?

You've posted a link, sometimes ago, but is not working anymore

Sorry, No I don't have the link anymore. I sold my X10D some time ago (my system finally got past it), so I only have a cursory interest in it anymore. I feel certain that a search of this forum should pull up something though.

At least, this is what comes out, from your original thread

Hi motzu',

You've got the schematics in this thread :

MF XPre troubleshooting

BTW the noisy problem was only my fault, not having rewired the inputs the proper way...

Thanks

I haven't found the thread searching on forum
