Front Layout and Racking Question

[Tillmann]

In the FAQ section of the website, someone wrote a comment about wanting to mount a couple of preamps in a one space rack chassis, to which was replied:

"Well, I don't know if it's a MAJOR sticking point, since the CH01 is perfectly happy with just two N72s installed. For people really tight on rack space, the best idea I've got for a 1RU, two-channel case is to use a Bud CH-14401 and cut holes in the cover for the transformers to poke through. I haven't tried this myself, though."

First of all, what is a Bud CH-14401? Next, looking at the specs on each of the SC modules with trafos, they all seem to be 1.5 inches or so in width. A single rack space is 1.75 inches high. Why would you need to cut holes in the top for the transformers? Only so that you could center the pots and switches on the front panel? This is actually a major sticking point for me as well as I would like to combine two of the N72's in a single space rack with either two other EQ modules or two A12's.

Lastly, it's difficult to see just exactly how these are layed out from the front view. I know that they are layed out in the same sort of proportion as on the pictures of the front panel of the CH01, but it would be nice to know exactly how the front view looks and to have exact dimensions of where each switch and pot lies in proportion to the entire width of the module including the transformer in order to do my own front panel layout. Does anyone have a jpg of the exact front view layout? If the centering is a bit off for my purposes because of the location of the pots and switches on the PCB in comparison to the physical width of the transformer and would in turn make the front panel look strange, does anyone have any suggestions for mounting the pots, switches, and XLR's externally from the PCB so that I can configure them where ever I would like on the front and rear panel in what ever sized rack I would like? Meaning, is there a good point to solder wires to on the XLR's and particularly the pots, or perhaps there are some little connectors that I could crimp onto wires that would then slip over the pots connections and then I could solder the wires to the PCB. The best would be a Molex connector of sorts, actually. Or would it just be best for me to find someone else’s 1272 PCB and do it all myself?

The N72 output transformer is just about 1.6" thick, too big to fit into the Bud CH-14401, which is only 1.5" high. If you can find an off the shelf 1U chassis that is a full 1.75" high, you could make that work.

E-mail me for a measured drawing.

If that's what you want to do, you clearly don't want what we're selling. You'd be much better off buying some old Neve BA183/283 cards and doing the whole thing yourself.
