#37 Presonus Audiobox 1818VSL teardown and troubleshooting (part 1)

Together with the pair of Konnekt x32's (one of which is dealt with in the previous write-up here), i also got one of these Presonus Audiobox 1818VSL's. Also sold as untested, but powered up and allegedly detected by a Mac, so i figured it couldn't have been too far gone (or fubar'd).

The reality of it turned out to be a wee bit more complicated than one might've hoped...

#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.

#35 Focusrite Saffire Pro 24 DSP teardown and repair

Yet another sold-as-faulty eBay catch - a nice little Focusrite Saffire Pro 24 DSP Firewire audio interface. The listing said:

"I bought this online and it is not working or it is not compatible with my computer. My computer is not recognising this audio interface. So I am selling it as not working."

 Fine by me. The photo of the back showed the Firewire port as looking quite pristine, so it wasn't a case of connector-inserted-upside-down. And for the price i won the auction for, it was worth the gamble. A frontal photo did show it powered up, so at the very least, it wasn't dead.

#34 MOTU Traveler mk3 teardown and repair

Hunting for faulty stuff on eBay has been fruitful yet again: this time, a MOTU Traveler mk3 Firewire audio interface. The reported issue was by now, the "classic", dead Firewire.

A pretty comprehensive little package, with loads of features shoehorned into quite a compact package - 1RU thickness / height, but only about 80% of the width.

#33 Superlux R102 active ribbon microphone teardown & reverse-engineering

By sheer luck / accident, the other week i refreshed my Facebook main page (or "news feed" or whatever), and the first thing i saw was an ad from one of the trading groups i'm in, about a Superlux R102 (mk1) ribbon mic for sale, for a measly 30e (~$32). The seller was in a (sort-of-nearby) town i was headed to just a few days later, so i jumped at the chance. Immaculate shape, fully functional, retails for about four times as much - why not?

#32 M-Audio (Avid) Fast Track C600 teardown & repair

This little bugger, an M-Audio / Avid Fast Track C600, was listed as faulty on eBay - description said it would no longer power up, regardless of it being bus-powered or having its own external power supply connected. Got it shipped for 30eu / $30, so why not?

#31 Warwick ProFET 5.1 bass amplifier teardown & maintenance

A local buddy just brought this German beastie in, citing a dicky DI output, and an unhealthy-sounding fan. Well, when i say "German", i mean the brand itself; as one might expect, it's "obviously" made in China, as it says on the back. But isn't nearly everything (else), anyway?

#30 Double Dock Day - HP HSTNN-I11X and Dell PR03X (USB 3.0) teardown

Right, so i had been on the lookout for a cheap docking station for my Dell Precision M4800 for a while, and the other week i stumbled across and ad on a local website about a clearance sale from a university - docking stations, laptop chargers, some desktops etc. When i finally got to their premises, instead of the $5-10 prices i expected, the guy there said i could have them for some coffee-change into the tip-jar, so i walked out with two PR03X's for a mere 40-50 cents or so - me happy!

The HP dock though, was about 15$, but came with a ma-HOO-sive 230W power brick, which is for another project; expect a teardown of the brick soon. Sadly the dock wouldn't fit my HP Elitebook 6930p (only the later xx40 Elitebooks), but that doesn't mean we can't take a peek under the skirts, and then resell it to make some of the money back, right?

#29 Tie-dyed acoustic panels

I know, it's a bit of an uncharacteristic topic for this (sort of a) blog, but despite the curve-ball thrown here, bear with me. It's for a good cause... As it were.

#28 Active full-range surround speaker project (BN96-12832 & TPA3118)

Since the "unofficial" theme of this blog seems to be repair, recycling and repurposing (more or less), i finally got around to getting knee-deep into this idea, which i started devising quite a while ago - a pair of "slimline" surround speakers.

Disclaimers:
 - No, these are not meant (or supposed) to be "hi-fi". More just for a bit of "ambient noise", if you will, for movies with 5.1 soundtracks. That, and possibly alternative monitoring for checking mixes.
 - No, these are not meant to go terribly loud. Due to, let's call them, physical constraints, they'll be placed at the corners of my sofa (right up against the wall, opposite the TV and the "mains"), so no huge SPL's are required.
