OK....We have at least 10 versions of this EQ.
I needed simple stepped one-here is my vision of this thingy :)
(I did it about 3 month ago).

So..... Carenhill inductor can fit here as well as mine.
Very standard things used:
Lorlin switches. Simple PCB. Second half of BA-283 used as make-up.
24V power supply and 2 bypass boards. Simple wiring.

Any interest?

I wasnt that thrilled when i read it, then i saw it and literally outloud said oh shit.......needless to say i wants ;D
 
mmm didn't see any tubes in the pics
so i guess this amazing pultec-neve is SS
can't wait to build one !!
Gimme my soldering dose
awesome Igor !!!!!
 
No fair sir, let me at least finish some stuff before I want something else... I'm already behind (broke) enough as it is!
 
OK :)
Yes, this thingy sounds really good and a way useful.
I am too lazy last time to build "Pultecs", so,
good idea to offer this as kit/PCB's here.

Here are preliminary docs, the schem is drawn rough a bit,
anyway, I doubt if there are people who are not familar with it :)
Will be re-drawn in more readable form.

Corel file for front attached as well.

The "difference" to other available PCB's is very simple assembly,
second half of BA-283 used as make-up gain stage, and it sounds really good,
so, many people who prefer discrete class A can enjoy it, as well as use tube make-up...

I think to offer a bundle: EQ PCB+Make-Up PCB+ Bypass PCB as mono set,
and same + power supply PCB as stereo set.
Inductors-yes, possible.

AND.......
Here is COOL thing.
This EQ is STEPPED. Not 21(23) steps ELMA's, BUT the steps are small enough, and
Lorlins are cheap but good working solution.....
So...
We have split (dual) primary input trunnies, like Neve line input clones from Carnhill.
We have as well "dual" secondary LO-1166.
Guess where the wind blows?
MS MODE PCB with relays. Let me know about this,
if you like to add LR->MS->MS->LR to bundle (the price will remain almost same).
I.e. there's LR/MS switch, EQ can be used in both modes....

Of course, the overall gain in MS mode will not remain same,
but it is possible to compensate with make-up switch.

Well...
Just write your name to estimate how many PCB's to order.....
Stereo bundle of PCB's will cost less than $160.
MS or Not MS (you can build this EQ without MS but add it later);
Inductors (roughly, MOQ is 20; the cost is about $22 ea);

 
Igor, you put me over the edge  ;D

Yes, i am in here too. With MS please.
