Ah yes. If interested, post here.

@ tomas1808: please mail/facebook/skype me your shipping address.
 
Finally!!!!
Decided!!!
Had prolonged meditation with EQ schematics  folder, when thought which EQ filter to use
in addition to 4K dynamics/T*****Ent D*****er combo for sidechain/audio, single band eq;
guys, nobody will guess what have I found, but this is absolutely hillarious drooling versatile ubersh*t!
They used for EQ gain... phase reversing schematic with pot/opamp!!! and have inf cut/14 db boost; every filter can be bell/shelve;
in reso shelve position it has 28 db/octave slope!!!!


Well, the add-on will contain: TD att/rel controls, EQ boost/cut, freq, Q knobs, and shelve/bell toggle (or pushbutt).

For routing, there will be 3 toggles:
TD: PREEQ/OFF/POSTEQ
SSLDYN: PREEQ/OFF/POSTEQ
EQ: AUDIO/OFF/SIDECHAIN

Seems it going to be TONLEITUNGSUBETRAGER for drums. I mean, good, without google translate.

For pristine guys, I leave channel's dynamics basic as it is.
All extra stuff will be at add-on external pcb.
I'm definitely interested in a pair, depending on cost...

The cost of 4k dynamics pcb set will be in $65 range; if we have more than 30 orders,
should go down for $55, regular registered airmail shipping already included in price.

Gold fingers is the thing manufacturers hate to do, and there are 4 pcb's at panel (mean tooling charges etc).
For 100 orders, it can be even cheaper, but we need half year preordering thread, I am out of this.
When I have 100% tested production pcb set, they will appear with some moderate announce at my online store.

However, more interest=less price, so, write here, I will know how many sets to order.

The add-on PCB will not cost much, I think, it is possible to keep it within $40 if there are 20 orders at least.

For mechanics, here are lowest possible prices.

Brackets are $28 each with machined holes +all hardware (bolts/nuts/standoffs);

For fronts, most of peopla liked 3.2 mm PCB, immerse gold, like 51X-F76 (my 1176 adaptation for 51X),
or like used for MixBuzz500; however, evil enemies posted somewhere kinda irrespective things
about antiaestetic PCB use as front panel;
(f*ck, why spell checker wants to change antiaestetic to antisemitic? bugagagaga, we need 4th Reich)
If somebody have something against cheap but exellent looking 3.2 mm fat immerse gold black PCB, used as front, lemmie know.
They should be in $16-22 fair range per frontpanel for 20-30 orders.

CDR file will be attached to schematics/pictures archive, for people who want it racked in 1ru etc
and/or use frontpanelexpress. And, maybe, there will be cool building manual from native English speaker.
Can put build pictorial, but leave me off from explaining how to solder resistors, I'm bad in this.

Machined aluminum fronts with engraving comes up bit high, mind, 2 sides, 3 tools, about hour of time each front;
0.15mm engraving bit can be used to make 3-5 panels than goes to trash.
However, if $70 per black anodized engraved alu front is ok, no prob, possible to make them topnotch.

Wow, Igor. You're a machine.  :eek:

Seems like there's a few things missing, I'm sure your re-design is awesome.

Let me know what is missing, I will add. BTW, you were working on SSL channel dynamics about a year ago;
progress? If you like to use my PCB's, feel free to mail.

Rechecked again THAT2252 versus AD536, absolutely same at any level within 20-30k.
Some db difference at 70kHz does not mind, imho.

Well, since I donate my free PCBs I might buy two for myself :)

Yep, I remember. At the moment I have the production batch of dynamics PCB's, first pair goes
to Germany and secomnd pair to Uruguay.

Cool. Questions, interested - post here.
 
Yep. Rackit PCB....

Good news.
Got nice PCB's, have to find time to check... and 4000CC pcb's will be available!

Checked both versions (THAT and AD) again channel compressor, close more than enough, IMHO!

Finished 4K CC good quality photo:
