Stereo, stepped, easy-to.... Pultec! /Neve'ish, porn pictures, MS-inside!

im in for a stereo set

 

[Igor]

Will be offered very soon at WM thread.

 

[JayDubrek]

I'm very excited about buying a stereo set....nice studio by the way Igor!

 

[JBVries]

In time for the Igor Birthday Special?  ;D wink wink, nudge nudge

 

[Tubefreak]

Anyone got an idea how to implement a gain range switch to go from aprox 1dB steps to 0.5dB steps?

Kind regards,
Maarten

M=L+R, S=L-R

How exactly do you implement mathematical equations like this in a circuit?    This is more of an electronic theory question, than a question relating to your kit, Igor.

 

[MikoKensington]

Mid is Left and Right signals summed.  But Side is better described as Left summed with reversed polarity Right.

M=L+R,  S=L+(-R)

Not sure if that helps any.

 

[Igor]

OK.... here is the schematic for MS/BYPASS board.

 

[Igor]

And, here is the board....
Separate Zobel networks and load added to each split secondary,
to preserve best possible transient response. The assembly is easier than the schemo looks)

 

[haima]

cool!  8)

MS = ?

sorry you lost me on this , eventhough its stated as obvious to others

(M)main , (S)sidechain  maybe ?,  just guessing.

 

[strangeandbouncy]

  nope, Mid and Side . . . . . .

 

[Igor]

Hope to find some time to connect missing stuff and test this set of PCB's...
Here we go:

 

[baadc0de]

mmm, looking good!

 

[ncoak]

nice!

 

[datune]

If possible, I'd like a full stereo kit with MS, thanks!

 

[Igor]

Hoho!
I will inform about tests results this week....For now, had a time to check MS board + BA283 makeup only
(with Carenhill outs and mine inputs)..... IT WORXXXX!!!!!
Have to install new improoved inductors on EQ board.....then listen....then, it is here!

 

[KasperNyhus]

beautiful....! I can't wait 

 

[Sylvain D.]

Igor, this looks great
Let us know how it sounds.

Hi Igor.

Great project. I'm very interested. Would it be possible to use Jakob's tube-gain-stage with your boards?

Cheers
