A couple new boxes finished. These both sound amazing, I'm very pleased, although the Jung-Markell stands out. In a brief test on acoustic guitar it really captured all of the natural overtones and harmonics that other preamps don't translate. The THAT1512 pre was close, very fast and clean, maybe just a touch bright sounding because of the speed and surgical precision of it.
THAT1512 pres on top, PCBs from mcs. Unbalanced outs, but plenty of room for add on balancing measures, thanks to Mikkel's great board layout. More people should consider these for a project, his kits are inexpensive and a quick build, despite the SMD gain setting resistors. I was proud that I only lost one (though I was scouring the floor at least three times for runaways), and easily subbed a regular leaded resistor.

Jung-Markell pre on bottom, my PCB design (and not a very good one at that, was difficult to work with). Jensen input transformers, Edcor outputs, with unbalanced output via switching jacks.
