X-LP version 1

[nando]

I have a X-LP which I will work on in the future.

Here are already some photo's.
















This is the power section... A lousy 4x 470uF capacitors. This screams for an upgrade. Only there is not much room! The capacitors are close to the edge of the pcb and x-lp. Maybe the future (bigger) capacitors must be placed on some funny angles.


I'm stunned... MF did place Jamicon capacitors other than 85C versions. This is one of the Jamicon TK series and are rated 105C (470uF 16V).











Yes! 105C rated capacitors here as well.


Underside of the pcb of the x-lp. The soot of at the soldering of the switch for MM/MC selection. There is possibly a repair of a track on the pcb.


This is a crop of the last photo. It looks to me like there was a repair of a track and the solderpoint.

I've replaced most of the elco's in the x-lp.

This is before the mod.


Power supply elco's removed.

I can't finish the x-lp because I failed to order one capacitor. I will do that in a next round of parts I will order at Mouser.


Replaced rca socket, power supply socket, diodes with UF4007.


New diodes



Capacitors at a funny angle because I misjudged the size and available space.


The whole power supply section. From 2080uF to 13200uF. Recipi for disaster?

Not a recipe for disaster..... it will be fine BUT I never like resorting to funky angling..... the closer the caps are to the regulators the better.... longer cap leads = lead inductance yada yada...... it won't be a biggie and will sound a lot better than stock (a lot better) so don't worry Nando.

As you have probably gathered, I'm not into "free form funky" cap placement and I always like to keep things slick and tight fitting...... using the best replacement cap that will "fit" into the space available. I know, we don't look at capacitors when we are listening to music but nonetheless I like to know things are tidy under the bonnet Especially important when providing a kit of parts..... it has to sound awesome AND be simple to fit.... so, parts selection, as you have obviously found, isn't as simple as pressing a "buy it now" button

I've worked on a couple of them (X-LPS) and the last one was Laurent Moureu's XLPS...... slightly (only ever so) different from the X-LP and here are the pics:

Before:



After:









Just look how close the caps are to the regulators:



A few close up shots of various sections of the XLPS:













I gave the enclosure a good wash and, voila!, as good as new!:

[nando]

I already bought the parts so they had to go in. I did measure the space but yeah.

The x-lps is not that different from the x-lp.

You placed samwha 135C instead of the Jamicon TK 105C. I went for the Panasonic TP 135C's.

Were those green epoxy dipped capacitors original?

Years ago i had an XLPS, i bought a trichord dino which was better sounding
When i upgraded the caps etc i got off mike, it sounded just as good as the Dino, more detail in the mids
Dont have either now but worth upgrading the inside of the xlp, there should be a thread i started on the subject somewhere on here from years ago

Yes, they were. Sorry it has taken me 2 years to reply to this Nando

No worries.

I havn’t used my xlp ar all for the last two years I think. My setup is so that my beogram 5005 is to far from my xlp that the sound is distorted. I think I should have putt my xlp close to the recordplayer and have a stronger signal over the long distance.

Soon I will be moving to another location and there will be another chance to get is right.
