New need diagram

[riviera72]

hello I just discovered. this wonderful forum. I have a x can since several years. I would like to find the complete diagram because my xcan stop working

Thanks

Thank for the diagram. 
How much uf is to much for the caps on the psu board?

Thanks

Oh my god!

You have gone WAY over the top there!!

Those huge Mundorf film caps and all the associated wiring aren't doing you any favours for starters (think lead / parasitic inductance).

You can safely remove C102 / C102 and jumper over the pads with a wire link. I would also tend to remove the 2 x Mundorf 560uF film caps from C110 and C210 and replace them with a 6.3V / 1000uF Nichicon MUSE non polar cap (or any other sensibly sized non polar electrolytic).

Before saying any more I have two questions:

1: How long was your V2 working for with those parts installed?

2: Is it totally dead or has only one channel gone? Please explain:

I, personally, have found that between 15,000 - 22,000uF on the PSU is the sweet spot. I haven't tried 47,000uF (in total) because that amount of capacitance won't fit inside a standard X-CAN V2 enclosure...... I doubt the capacitance is causing your problem. I would go "99%" with it being a broken pad to trace connection somewhere..... can you take some better (higher resolution) photos of what's going on UNDER both boards? The photos you've uploaded are pretty murky, try to get some good ones taken and I'll see if there's anything obvious that's wrong.

Have you checked the obvious? The headphone socket is a well known problem area..... it is not physically connected to the fascia and the solder joints DO fracture / the naked eye won't see the break....... Try resoldering the headphone pads for starters.

I tend to keep things simple (like parts that will fit into an V2 enclosure whilst still be a MASSIVE upgrade in the SQ dept.) but good on you for experimenting "outwith" the confines of the stock X-CAN enclosure, respect to you for that.

This is the setup I employ inside X-CAN V2 enclosures...... there are a few underboard tweaks that are not shown (I don't want to make ALL my hard work public) but they are sympathetic to the X-CAN enclosure and don't require a shoe horn to employ them rockgrotto.proboards.com/thread/1961/work-progress?page=22&scrollTo=146016

All the best,

Mike.

thank you again the problem was the potentiometer and the jack, I take the opportunity to change some parts

[PinkFloyd]

That's looking a lot better! I thought it may have been a bad / intermittent headphone socket joint..... glad to have been of assistance

Is it sounding better now?

Best regards,

Mike.

That’s something else!

It works again but the suggestions Mike did might be worth looking at.

Is it sounding good?

[riviera72]

it plays very well the sound is very accurate, I think the treble is a litle piercing , the sound is very similar to my alo continental dual mono.
