Sontec EQ

[JeromeMason]

Can someone point me in the direction for the Sontec EQ kits or PCB's? I've searched everywhere and everytime I get a lead the link is dead. I just need to find where to buy the PCB or if there is a full kit.

I'd really really appreciate any help,

Thanks!!

i have a set (pair) from fabio with most passive parts that I wont be getting to this decade

Do you mean something like this

Will be available for one week as whole tested kit.

Looking at the PCBs, your circuit will behave significantly different compared to a Sontec EQ. Good luck with your endeavour.

Harpo: You have an eagle eye  Can you tell me why?

 

[Harpo]

Center tapped potentiometers come with at least 4 pins, your pcb has 3 holes for this pot.
One DIL-8 (probably dual) opamp on filter board. Different requirements for these opamps might/will not have them in the same housing. Not knowing parts values of your corresponding circuit behind, at least these discrepancies seem obvious.

In other words: eagle eyes... ;D

I'd really love for someone to make a kit for the Sontech or the Nightpro..... I'm really needing an eq for my buss and theres basically nothing out there besides eq's that add something.... I just want clean, maybe an air boost like the Nightpro. Does anyone anywhere know of a kit I can look into buying??? It seems Igor was the only one doing the Sontech, and the guy that was doing the Nightpro doesn't do it anymore.

I honestly would love to have the Nite eq.... that's a really great eq, and they are not expensive in the least bit. Seems like someone would get this going, especially with all the hybrid rigs these days.

I think there's something brewing over at the DIY Racked forum that might be worth checking..

DIY Racked forum , is not a guy I'd trust [ and especialy not with my money ]

note the sontec needs some more expensive pots and will be more so overall than the nite eq , [ a cheaper cost eq ]
also there was an orban designed DBX  " project " eq that was respectable , parametric .

note the sontec needs some more expensive pots

Thats exactly where I am at. I wanted to hold off completing a design until I knew where to source the pots, but I have not had any luck yet.

Going for round 3 with Alpha. Omeg is much more expensive, but easier to communicate with, so I may try them after.

Surprised there are not more people looking at the Net EQ, which is as good if not better....

I've looked into this, but I can't find a discussion page that tells you where and what parts are needed, and where and who provides the cases. I see the PCB's, that's the easy part, but I cannot find everything else like you would in a normal build thread. It's seems like Igors Sontech was the last one to provide all of that for an EQ of this type.

Unless.... someone can point me in the right direction, I'd be glad to give the net eq a try. It's a lovely design and I've heard nothing but great things about them as well.

Harpo: 4 pin in pot is earth

Harpo: 4 pin in pot is earth

No. The 4th. pin of the single deck pot needed is the pots center tap connection to the resistive trace. In this circuit this resistive trace center spot is then connected to 0V reference voltage. An off axix 5th.and/or 6th. pin will connect to the single deck pot housing for shielding purpose.

 

[lubosko]

Yes I understand. We talking about this schematics or ... ?

 

[Harpo]

Schematic shows an -what I'd call- 'Igortec', Igors implementation of an EQ partly similar to a Sontec MEP-250A.
Center tapped level pot function is nearly the same (without the 7K5 resistors connecting to the level pots outer connections and shape setting parts values, borrowed from a GML circuit). To the best of my knowledge noone ever built a kit of a Sontec clone and I don't understand the desire of sailing under false flags. At least he could have called it maybe Songtec in order to differentiate from Mr. McNeals builds.

the matter is that for being an original Sontec MEP-250A are needed the original sontec opamps inside it, we cannot speak of an original sontec without them in any case.

 

[lubosko]

Yes OK, Songtec sounds pretty good  My design is based on this schematic, and I think it's no bad sounding EQ. Maybe the best ideas from both worlds.
