This is a continuation of my Sony Racking Job. Click here for previous article.

Things are progressing nicely. Some photos.

Finally cut the hole for the EQ section... took about 2+ hours... it's a pain doing this. And I have to be careful not to make the square holes too big because the tolerances are very tight.



Some closeup photos of the Preamp and EQ module.









And here's a picture of my 1st Sony MXP preamp (white case) and the 2nd unit I'm currently building (black case).




Next steps:

1. Drill holes for the output transformer. I'm using an output trafo that came from an MCI console.

2. Build +18-0-18 PSU with 48V phantom power... drill holes on case for PCB and toroid transformer.

3. Wire everything!

I have 4 Mic preamp Sony T-9412-053-1 and 4 EQ Module.
I am very interested in continuing to build with this tutorial in 4 1U racks, like your project.
I consulted the guide that has published in http://www.fivefish.net/diy/sonyconsole/default.htm, and with these photos, change something the general outline.
I can not find the general outline of all connections, ie between the preamp module and eq, and also among all parts of the project in general.
Nor is that kind of trim level and that value is used.
And the draft published in www.fivefish.net here are more things that do not come in the draft.
You could publish or send me the general schema of connections between everything, and a list of parts used?
Thank you in advanced
