#36 TC Electronic Digital Konnekt x32 teardown and repair

We're having a "productive" period, as it turns out. This time around a TC Electronic Digital Konnekt x32 audio interface / digital patchbay is on the chopping block. Or on the operating table, rather - i do indeed hope to repair, rather than dismember and mutilate this thing.

I managed to catch this, along with a twin of its, for under $200 / 200e delivered, as a "job lot", both sold as untested / faulty. The first one was shown powered up and possibly working fine (several LEDs on the front panel being lit), so potentially fine, pending tests. This second one though, not quite so much - only the blue LED halo surrounding the power button lit.

#21 SM Pro Audio TB202 dual tube preamp / channel strip modding & upgrade

<Further developments can be found in parts two, three and four>

I'll admit, this was a bit of a lucky catch, in that it was mistakenly listed in the wrong eBay category, but one i "stalk" for good deals on certain faulty bits of audio gear. It was up for auction, there didn't seem to be much demand for it, and i ended up winning it for a mere 21 euros. About as much as the shipping for it ended up costing, oddly enough.

But still, even for some 40-odd bucks, not a bad little unit. Two channels, a (bare-bones-ish) compressor on each (1.5-10:1 ratio, 1ms/5ms attack, 500ms/1500ms release, at least according to the specs in the manual), as well as 3-band EQ (80Hz shelving / 1.8kHz bell / 8kHz shelving), and there's a tube / valve involved in the circuitry as well. If nothing else, i figured it would do nicely as a bass DI (or even an overdriven preamp, once some internal re-wiring is figured out and done).
