Hi Igor, will ordering one PCB for the MixBuzz1 here (http://market.diyrecordingequipment.com/MixBuzz1-PCB-set,name,100171,auction_id,auction_details) and buying the parts from the BOM provided by evilcat here (http://www.groupdiy.com/index.php?topic=41654.msg560730#msg560730) give me everything I need to build the MixBuzz1 with all the extra's (sidechain, turbo, blend etc) or do I need more?
@ thesystem : funny nickname!
I haven't checked one by one the bom supplied by Evilcat, but it looks OK.
Updated and rechecked BOM is here:
http://ij-audio.com/downloads/mixbuzz1_docs_v2_4.rar
When ordering relays, be sure they have more than 800 Ohm coil resistance.
Easy to check with datasheet. One of Farnell P/N'r (relay) in my older BOM was wrong.
I did not included in my BOM XLR's, knobs, meter and power switch. Many options, at your choice.
The rest is in BOM.
Mixbuzz1 has all possible options for all available today build variations of SSL 4K master bus compressor:
dual/single detector, sidechain hi-pass/thr@st filters, MIX (or blend/C&B), stepped/pot variable attack/release,
dual release control, soft/tight attack/release.
It is not simple build, however, if you check the documentation, everything is in very logic order.
Hope you will enjoy this compressor as many people do.
We still have 2-3 basic kits, +filters, +MIX, +LED meter addons. Feel free to contact me for full kit.

Hi "The System !!!"
Everything you need is in "my" BOM. Nearly everything from Mouser, plus some things like power xfrm, case from a local French supplier, it is clearly noted in the excel sheet.
My relays are maybe wrong, I'm not sure they have more than 800R coil resistance, but except that, I achieved a complet build with this exact BOM. You could use my Mouser Shopping Cart if you like.
Good hunting ! ;D
Best,

It was 407€ from Mouser, plus 200€ from Radiospares in France (RS Components).
hi Igor mixbuzzy man,
finished 5 mixbusses before summer , they where around belgium festivals with different mixguys/bands.
they all loved it !!!!! drumbuzz and master!!!!
right now its working its mid magic on the master for studio mix, they love it to..
guess what , sound/ system engineers are caling me for more off these ... the saw /hear them on the festivals
maybe i need 5 more to solder if i got the time .....
thanks
jan from belgium
need help on your digital controlled eq? got a eq 200 here from element 78/summit audio

Still waiting for my shipment to arrive.... been a few weeks now... ;D 
Very important update.
Due to 90% of people who built this compressor did it with 11 steps attack and release switches, the new PCB's are done by this way.
All is same, but easier wiring.
http://ij-audio.com/downloads/MB1_docs_2_5.rar
+12V regulator's heatsink was changed to bigger one.
LM3914 LED current setting resisters were changed to lower power consumption too.
In case of whatever: use 12V relays with 700Ohm...2kOhm coil resistance, to reduce current consumption.
Front for use with Uraltone 23-step switches (the controls are bit moved to get space for 23-pos switches):

Hi Igor,
greetings from Lithuania. Sorry for noticing all that great job You did here so late! Probablly I was too busy for making me GSSL's
Is there still possible to order 1 PCB with Power and IN/Bypass/Comp lenses?

Greetings from Israel. I grew in Minsk, so, we were neighbours.
Yes, for sure! ij-audio.com/store for pcbs.
I have the blank lenses only for this moment, but in case of whatever, contact me on facebook/skype (kapelevich igor).
