Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

Hi im new to this thread and entirely new to threads all together but i was hopping on elaborate explanations to your issue hope u can shed some light cause this is what is my issue with my xone 92 as of today i noticed something weird with my mixer and i love it to death as i'm sure you do yours !
First off the signal seems to change even when the filter is not engaged and i twist the filter knob, then even when applying wet\dry with the filter not engaged it changes the sound and last my hpf bpf and lpf are not cutting off like they used 2.
does this sound like a cap issue ?
PLZ some light to my deep and dark tunnel of desperation .?

Wow thx guys for the help i hope this is the solution to my filters not working correctly .

Hi there, I am about to undergo the same project. Glad I found this post!!! It looks like it's been a couple of years since you did this, were you able to fix your PS??

Also in case anyone would find it helpful, I found a schematic of the PS.



I'm ordering my caps from Mouser, hope to get this going again soon!

Cheers

oops your right, no charge, my bad too many tabs open with components, *laughs* thanks, I will order your choice, good to know I hadn’t picked something unworkable though, thanks again

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

The one you linked to has a 115mA ripple rating. From what I was able to find out that's the same as the original. Just 85°C though.

Shouldn't be a problem. The one I linked has higher specs, but if it's a US import (expen$ive shipping) that's not gonna help lol
BTW where does it say that? Couldn't find anything

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

The higher the ripple rating the better. At the very least the same ratings as the original cap. (It's an "up to" figure, like the voltage.. It'll work fine up to XYZ mA ripple current without blowing up by overheating)

ESR on the other hand should be as close to the original as possible to prevent problems. Lower ESR generally doesn't hurt, as long as you don't go too extreme.
Replacing a 0.048 ohm ESR cap with a 0.036 ohm ESR one shouldn't cause any serious problems.
Going from a 0.048 ohm ESR cap to one with 0.012 ohm ESR (or even less) most likely will make something go out of whack.

Could I use my choice without problems?

I can’t find the ESR rating for it or the original, but the one you list is a USA import and I get charged a handling fee of £15 from Farnell.

Very informative thanks so much, I hope you don’t mind but I PM’ed a little informal health info since you have been so kind sharing your knowledge, and I cure colds and coughs quite often I hope it’s of use.

Had such an "ESR problem" just a few weeks back. The caps I used in a LCD TV PSU were too good in terms of ESR, which made the whole thing whistle/whine and run much hotter than before. Replacing them again with slightly "worse" caps (higher ESR ; closer to the originals) made it work as if nothing happened.

I'm feeling a bit better, but I'm still on my "way in" so to speak.
My bro has been coughing his lungs out.. he just can't stop it. I fear I'm gonna end up the same in a few days or something :/
So far it's just a runny nose + headache.. maybe I'll get lucky (famous last words.. )

5. (C57 board location). Samwha SD series, Model R7A, 400V 10uF 105°C (M) - Width 10mm Hight 21mm

https://cdn.badcaps-static.com/pdfs/...5cffd5baf9.pdf

I have noticed the ripple rating for the original is 115 @ 120hz-
Hence my replacement choice of-

http://uk.farnell.com/panasonic/eca2...0uf/dp/1907181

your choice-

http://uk.farnell.com/panasonic/eeue...0mm/dp/1673487

has a rating of 150 @ 120Hz

Your choice is much cheaper and seems to last much longer under operating conditions, my question is, how much of a slave to ripple current accuracy (to the original caps) should I be with my replacements?

: ) - thanks again for all the help, hope you're feeling better : )

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

god.. I'm waaaay too slow today

You good sir are frakkin’ awesome today!

Thanks and I shall put a "good health unto thee and thine kind fellow" wish in the cosmic post to you immediately, the moment i’m done peeling those stamps of the last one I got sent.. - but seriously thank you and get well soon!


Yippy now to huff on some solder fumes while waiting for Farnell to send my goodies..


Corrections for others reading this looking to do the same thing -

Cap number 5. (see picture) (C56 board location) thus Cap 6. (C57 board location) is correct : )

Thanks to all the contributors of this here thread and this amazing forum in general!

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

Despite being a bit sick.. here we go:

1 (C57 board location). Samwha HC series, Model R3D, 400WV 68uF 85°C (M) - Width 22mm Hight 20mm

As for the primary cap (the 400V 68uF), this one should do. If you really want a 105°C cap in its place, that one should do the trick if you have enough room to fit a 30mm high cap (and put the PSU where it's supposed to go)

2. (C64, C65, C67 board location) Samwha WB series, Model R6A, 25 V 470uF 105°C (M) Width 16mm Hight 10mm

http://uk.farnell.com/rubycon/25zlh4...25v/dp/8126461
---

4. (C61, C62, C58 board locations). Jamicon 324C4(M), 63V 120uF 105°C (M) - Width 8mm Hight 16mm

Need a series. I'm guesstimating from the pics that they're WG series, but there's no 63V 120uF in the datasheet. Much less a 8mm dia one

Doesn't prevent me from finding a replacement cap though

6. (C57 (?) board location). Samwha SG series, Model R8E, 50V 10uF 85°C (M) - Width 5mm Hight 10mm (might be 11mm hard to tell)

http://uk.farnell.com/united-chemi-c...ial/dp/1220672

just grab the right quantities and you should be set

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

50v 10uF sounds like a startup capacitor, you can use basically anything there. But make it 105C.

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

Cool beans, I shall add those replacements to the basket : ) now I just gotta get the others checked by someone, and look up a replacement for

6. (C57 board location). Samwha SG series, Model R8E, 50V 10uF 85°C (M) - Width 5mm Hight 10mm (might be 11mm hard to tell)

And then I shall be good to go.

Thanks Th3_uN1Qu3

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

I have been unable to find a data sheet for the Jamicon WG series that lists the 63V 120uF 105°C can anyplace on this here intereweb thingy, so I have no way of knowing what the ripple current rating was, but I'm gonna guess it was roughly the same as the Rubycon LZ series of the same stats

Rubycon LZ
120 8x7 380
120 6.3x11 405

I would say it is closer in can size to the 6.3x11mm can so I'm gonna go with 405 for the ripple.

I would really appreciate it if someone who can spare a minute or two could check these for me and tell me if I have missed anything, or made any noobish mistakes before I order.


4. (C61, C62, C58 board locations). Jamicon 324C4(M), 63V 120uF 105°C (M) - Width 8mm Hight 16mm

This is the intended replacement

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

Panasonic makes very good caps, no reason to search for Rubycon if you already found Panasonic.

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

Ok so today I found these Panasonic as a replacement for the number 5 caps, anyone know of Rubycon Caps of the same specs, I couldn’t find any on Farnell but that doesn’t mean they aren’t there...

5. (C57 board location). Samwha SD series, Model R7A, 400V 10uF 105°C (M) - Width 10mm Hight 21mm (ripple 115 @120khz)

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

Thank you Th3_uN1Qu3 very useful info.

I guess all I need now is links to the Farnell site for as many of the replacements as possible, and if some kind person could list what other caps I need I will source the rest myself.

Sorry if I am being demanding, I’m just learning at this and the guidance and assistance is very much appreciated. So glad I found this awesome forum, you guys are so friendly to share your expertise. - Thanks all : )

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

It's recommended to match the ESR as close as you can. Lower ESR will certainly not hurt in terms of filtering, but it may cause the SMPS controller to go crazy because ESR changes the transfer function of the feedback loop, and that would open a whole new can of worms.

[firespace]

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

Hi,

Just wondering would a lower ESR rating than the original component put more stress on components down stream? Should the ESR be as close to the original, or should I seek to make impedance as low as possible in all the replacement Caps?

Thanks,

FS.

Re: Allen & Heath XONE92 DJ mixer PSU board - (003-233JIT)

Other than Farnell, which I understand is part of Newark Electronics, I'm not aware of another UK-EuroLand distributor like Digi-Key. You might see what Avnet-Abacus might be able to do. It might not hurt to ring up Rubycon's Amsterdam or Munich sales offices to see of they have any suggestions. Also, maybe look on the sites for Panasonic/Matsushita, Nichicon and United (or Nippon) Chemicon to see what distributors and sales offices they have in EuroLand. If you do much repair work, developing sources for stuff would be a good time investment.
