DIY Mic Pre Kits, Lunchbox Mic Preamp Kits, Power Supply Kits

Hello! I'm getting ready to make my foray into preamps outside internal mixer pres. I've begun fixing tube amps as a hobby/side-job-for-friends and found that soldering is actually fun. I came upon fivefishstudios.com off googling "build your own preamp" and I am really intrigued by the circuits. I'm planning to get the 2 SC1-MK3 deal with the PSU and PT first and then order the X-12 duo. The timing is dependent on how Christmas shopping goes, though.

My real question is, are there measurements or templates available for drilling the chassis I come up with for these units? Also, would a four-in-one introduce more possibility of interference/other random electrical issues over having two separate rack units?

Generally, I prefer to conserve space if possible, but I definitely want good function! If I can get them all into a 1U rack with good function, that would be pretty neat. If that's the case, would one PT cover the power needs of the unit? I am a little concerned about being able to drill for those LEDs, but I can always cut a new case if I screw it up, I suppose.

Thanks for making it so affordable to get quality audio equipment!

Here's the front panel measurements for the SC-1mk3

>> Also, would a four-in-one introduce more possibility of interference/other random electrical issues over having two separate rack units?

There are no interference problems. My mk2 fits (4) in a case.
But the mk3 has a wider PCB and so only 2 channels can fit in a case.

>would one PT cover the power needs of the unit?

Yes. The preamp is very "Green" in power consumption... You can power 8 channels with a small 30VA power transformer.

Ok, thanks for the info. If I go with a 2u chassi, the mk3 seems like it will fit vertically (according to the measurements?). If the x-1 is similarly sized, I can fit 6 units comfortably.

If you go with a 3u, it will fit vertically. (i.e. same height dimension as an API lunchbox).
