    Behringer DDX3216 repair / repurposing

    Last week, i was fortunate enough to grab one of these babies off fleaBay, for roughly 100gbp (~120eu, ~150$). I had been "hunting" busted digital mixers for some time now, to "scavenge" the (100mm) motorfaders in them

    I dream / plan of someday putting together a DIY DAW control surface, employing some bits & pieces from the MidiBox project ( www.ucapps.de ). Aaaaaaanyway...

    Today, the UPS guy finally delivered the pretty big box. The listing said it had been partially disassembled but with all the screws included, and so it was. All of the screws had "escaped" from the ziploc they were in, but i didn't see any holes in the box that they could've slipped through, so i think none are lost.

    Instinctively, without even giving it a second thought, i went all Dave Jones on it (EEVblog, "Don't turn it on - take it apart!..")

    All in all, a pretty decent piece of gear, i'd say. What i could notice were AKM ADC's (AK5383, i believe), four Analog Devices SHARC DSP chips, an AMD CPU (Elan SC300-33KC), TL062 and NJM4580L (SIP package) opamps on the input - hey, it's still a Behringer

    Sure enough, even "only" through the ventilation slots in the PSU sub-casing, i could see bloated / vented caps. CapXon primaries, a whooooole bunch of Xunda on the secondaries, and a handful of further CapXons. This'll be quite a job, if only due to the sheer number of the lil' buggers

    Not sure when i'll actually get around to recapping this sucker, got a LOT of stuff on my mind / hands these days, plus i'll have to check my stock of jap-caps. I might have to place another order with PCMCS on the aforementioned fleaBay

    In the mean time, i snapped a couple shots (8MPx) of the relevant views - the underside of the "lid", the boards "inside" the casing itself, and the de-lidded PSU, in all its bloated & vented "glory"

    Re: Behringer DDX3216 repair / repurposing

    "For what it's worth", i removed all the electrolytics last night, from the power supply. Mostly Xunda TM, a few small Xunda RH, and a further couple of Xunda "VENT" series(?), plus a handful of CapXons. I couldn't be bothered with the two primary caps - despite their crap(xon)ness, the're not bulged, so they oughtta be fine.

    Either way, the list would go like this (skipping the C-marking) :

    Xunda TM 1000u/16v (52mohm, 1.3A), 10pcs - 13, 14, 15, 16, 19, 20, 21, 22, 70, 71
    Xunda TM 2200u/10v (38mohm, 1.6A), 6pcs - 37, 38, 39, 40, 43, 44
    Xunda RH 10u/50v, 7 pcs - 7, 27, 33, 35, 49, 57, 74
    Samxon KF(?) 47u/25v, 3pcs - 6, 26, 48
    Xunda ?? 220u/25v, 2pcs - 32, 34
    Xunda ?? 470u/35v - 73
    CapXon KM 220u/50v, 2pcs - 55, 56 (phantom power)
    CapXon KF 1000u/25v (45mohm, 1.4A), 6pcs - 60, 61, 62, 65, 66, 67

    Earlier today i browsed through "egekecu"s fleabay store, and ordered a whole bunch of caps for this (plus "spares"), so i'll have to get back to you on this in about a week or two, after they arrive

            Rubycon YXF 330u/50v
            Rubycon YXG 2200u/10v
            Rubycon ZL 330u/25v
            Chemicon LXZ 560u/35v
            Chemicon KZH 1200u/25v
            Panasonic FK 1000u/16v

            I already replaced the 10u and 47u with caps i had in stock already (Nichicon PS and Rubycon YXF, respectively)

            Just for kicks, i checked Farnell prices soon after placing the order, and, even though they didn't seem to have Chemicons (then again, i didn't look very thoroughly), "just" from the Rubys and Pannys, i saved 38 euros (~50$). So yeah, i'm quite happy

              very few places stock NCC.
              i'm always suspicious when i see them on ebay or in small supplers.

              i'm trying to go all pany these days, they are a lot cheaper than rubycon since ruby put it's wholesale prices up.

              not sure i would have used FK though.
              the relativly new FR have similar esr to fk/fm but much longer life - and usually cheaper!

                Well, as i said, i only had egekecu's stock to choose from I've seen him recommended around here several times, and i actually grabbed a bunch of Sanyo caps ("NOS", taped) about a year or more ago, and it's all good

                  Behringer Pro Mixer DJX-750
                  by Longon
                  Hi all....I have been using my Behringer mixer quite comfortably for a number of years now and generally it's been trouble free apart from a replacement crossfader. Recently input three channel fader began to bleed a little and causing the mixer to light up like a Christmas tree! I realise the unit is ageing now and although I'd put some hours on it over the years it's not been abused. Following the issue I planned on replacing the faders and ordered the necessary parts. In the meantime whilst awaiting the replacements I continued to use the mixer up until the channel fader started to give feedback...

                  Behringer Eurolive B205D repair - help identifying transistor
                  by magneh
                  Hello
                  Got this speaker from a friend , defective. Power led comes on and off , in a loop.
                  Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
                  After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.

                  I tested powering it up without the IC, and the speaker turns on and stays on, and works fine

                  Still, I need to replace this transistor....

                  Behringer F1320D Floor Monitor (300W)
                  by welldigger99
                  Hi Guys,
                  I need to replace the dual rail power supply in this unit (board damaged irreparably - by me!).
                  I have the schematic (attached) - but it does not (unhelpfully) show the value of the Pos and Neg rails.
                  Someone has suggested possibly + and - 42V, but as the smoothing caps are only rated at 50V this could be a bit close to the mark.
                  I am hoping Alxxxxpress might be able to come to the rescue and I am thinking somewhere in the 32V 8A region? Any suggestions/observations would be welcomed.
                  Many thanks.

                  Hi, I have few questions


                  1. few of my pots on mixer are turning so hard, I tried to clean them and spray some DeoxIT Fader spray in it, but it didn't help. Is there any way to put some grease inside that pots whole that is on the side instead of spraing in it ?

                  2. Or is it just simpler to replace them all with same ones ? I am not into pots, so am I able to put some better quality ones or it needs to be same one as they were default ?...
