#81 MOTU Traveler teardown & upgrade

As a follow-up to the recently posted MOTU Ultralite teardown, i had to grab this as soon as it popped up in my search results, because it had a price i couldn't ignore or refuse, and it had the ideal feature set for recording my band's jams and rehearsals. While the former had most of the features i needed in the 828mk2 i had been using, but in a smaller form factor, this Traveler packs more of the features i need (two extra mic preamps, while retaining the -10dBV/+4dBu line inputs with optional 6dB boost), in an intermediate form factor, as well as having a full 53dB of gain available on the mic preamps, but without weirdo custom potentiometers to wear out. Just about best of all worlds, really, especially for the paltry 85e this cost me. And as the cherry on top, it even has a separate battery input - hello, fully mobile recording sessions...

 

 

#80 MOTU Ultralite teardown

In an interesting turn of events, i actually did NOT get this one as faulty. It was more to relieve one of my 828mk2's from rehearsal-place-recording duty, and on the other hand, i managed to get it for quite cheap. In the context of, faulty ones had similar asking prices, so there's that.

#79 Focusrite Saffire 6 USB 2.0 repair

 Ok, this is gonna be a bit of a quickie. Basically, i got this one ridiculously cheap as well, with the intention of repairing it and gifting it to the new singer in my significant other's band, in order to facilitate more productive creative work. Just like the first one i did a teardown on and then modded, this was sold as faulty, but with more... obvious issues, let's call them.

#75 Focusrite Scarlett 2i4 (1st gen) teardown & repair

Perhaps a bit anachronistically, only *after* getting my hands on the previously-torn-down 2i4 gen2, i also came into the possession of a 2i4 gen1, that was no longer being detected completely / correctly by the computer. But hey, better late than never, right? I also grabbed a working one (because the price was near-irresistible), to have a known-good source for the firmware, in case that was the issue.

#69 Focusrite Scarlett 2i4 (2nd gen) teardown & repair

For a little while now, i've been thinking of "upgrading" from my old-but-modded M-Audio Fast Track to use as an in-ear monitor amplifier, and the Scarlett 2i4 caught my eye. The mono/stereo direct-monitor selection, as well as the hardware-switchable pads on the inputs made up just the right feature set, in addition to it being usable as a mobile recording interface. As it happens, just the other week, mere days after having saved an eBay search for 2i4's, an email notification revealed a 2nd gen allegedly-faulty unit being up for sale from Italy. I quickly asked the seller about shipping costs, and ended up sealing the deal for an even 50e. 

#62 Jamo Sub 200 modding

For background / context: https://mehlau.net/audio/multisub_geddes/

I had been off-and-on "hunting" for a twin, for my Jamo Sub 200 that i bought and revived years ago. Partially for SPL reasons, partially for the multi-sub approach mentioned above, and most recently, for actually sitting my couch on top of the subs.

At long last, a couple months back i finally found one locally, and in matching black finish. And with the 5.1 Jamo speakers it came in a set with, to boot! Those might get reused / repurposed later, (i'm thinking, in a manner similar to one of my previous projects).

#60 MOTU 8M teardown

Well, this one's a "biggie" - i had been lusting after one of these for a few years now, but the price was (and technically still is) on the prohibitive side, retailing at ~$1300-1500, depending where you look. Fortunately though, i've been stalking eBay off and on for one of these, and a used one happened to pop up just the other week, on auction. To my amazement and delight, despite there being at least 6 other "watchers", i was fortunate enough to win it for the opening bid, ie. about half the price of a new one.

#59 MOTU 828 mk2 teardown

Even though this is the 4th or 5th of these units that has gone through my hands, looks like i never documented a teardown of one - shame on me! Time to rectify that issue then, wouldn't you say? I grabbed this one off eBay for about 60 bucks or so, delivered. On one hand, because it was pretty dirt cheap at this money, and on the other hand, because it will be involved in a project idea i had a good few years ago. And yes, "as usual" (by now), this one had a busted Firewire connection, but for my own (nefarious?) purposes, i don't need that anyway.

#58 Behringer FirePower FCA1616 teardown

Long time no see, eh? Well, what can you do when the new job's kicking you in the rear end? Regardless, new patient on the table this time around - A not-that-often-encountered Behringer audio interface (now discontinued, "obviously"). I took the gamble on it primarily because it was cheap, secondly because i wanted to take a peek under the hood, and somewhat connected to that, curious about if and what "magic mojo" might the touted Midas preamps contain.

#57 Apogee Ensemble Firewire pt.2 - the repair

I was considering making the previous post about the repair as well, but once the teardown part of it was done, i decided it had gotten long enough already, so here's the testing and (hopefully) repair of it, separately.

#56 Apogee Ensemble Firewire teardown

[[[ Repair can be found here ]]]

This came up on eBay the other week as faulty - inputs 1/2 and outputs 1/2 seemingly dead. First instinct was, 'obviously', look up photos online in the hope of finding some internal shots. A few minutes later, bingo: four CS4272's in there. Now, what're the odds one of them is handling the bad pair of ins & outs? Quite a bit higher than the analog input of one, and the analog output of another to be bad, wouldn't you say? But let's not get ahead of ourselves (too much), and take things one step at a time...

#55 Focusrite Scarlett 2i2 (1st gen) teardown & modding

I had fiddled with one of these a couple years back, but here's another chance to take a look inside a (1st gen) Focusrite Scarlett 2i2, their second-smallest USB audio interface of the range.

#52 Solar A2.7 & Fishman Fluence Keith Merrow, part two

Aaaaand it's back! Not because of technical issues though. Due to chance, and the limited speed of international shipping, only the day after the owner got his guitar back, did the Fishman rechargeable battery-pack get delivered, just only too late to include it in the previous operation. But no matter, this should be far less involved than that.

#50 Philips HTS7201 Soundhub Home Theater (2.1) teardown & repair

This just came in, with the symptom description of "will no longer turn on". Fair enough, sounds like a power supply issue then. Apparently this retailed around $400-ish when new (according to a 2012 review i found online) - not exactly bottom-of-the-barrel, but it's still very much in the mainstream/consumer range, so i'm expecting crap caps to be the root cause. But time will tell.

#49 Joyo ZoMBie, part two - analysis and repair

It took the best part of an evening and a couple hours the next day, but i managed to lift the schematic for the whole preamp board. I also recreated the board, but that was mostly for sanity-checking. I used all the same component designators, but didn't bother measuring all the dozens of small ceramic caps, because there's only SO far i'm willing to go...

#48 JBL Charge 3 Bluetooth speaker teardown

This JBL Charge 3 came in last week in need of a micro-USB (charging) connector replacement. First thing i did was to look up how to take apart the thing, and the good people at iFixit had a comprehensible enough guide.

The connector board is totally separate from the mainboard, so the "repair" part was trivial, and done within minutes. But the more interesting stuff lies deeper inside. Sure, my photography may never get to be quite as pretty as iFixit's, but on the other hand, you're not here (just) for pretty pictures, are you? You're here to see what makes things tick. Or at least that's the curiosity that drives me to take apart stuff like this.

#47 Joyo ZoMBie guitar amplifier teardown

My bandmate got his hands on this Joyo ZoMBie about a week or two back; it was sold as faulty. No idea how or why, but there's something dicky with the tone control - on some power-ups it works fine, but sometimes quits working (ie. sounds like the setting got stuck at some random point along the travel of the knob), no matter how much you twist it. Power cycling sometimes helps, but inconsistently, and even if it does, it just "gives up" again, sooner or later.

#46 Tivoli Henry Kloss Model One teardown & repair

A client brought in this Tivoli Model One the other day, with symptoms of (lots of) noise. Once again, i went against the mantra of "don't turn it on; take it apaaaah't", but this time, for good reason - the thing isn't mine.

#44 Ram Audio S6000 teardown & repair (rebranded as LD Systems SP 6K)

A good buddy and neighbour of mine had one of his amps kick the bucket in the middle of a gig (one i was helping out on, as well). On the bright side, noone noticed, only when turning-off time came. The beast in question was one of his two LD Systems SP 6K amps (rebadged Ram Audio S6000).

#43 Focusrite Scarlett 18i6 teardown

As it turns out, i hadn't done (or at least documented) a teardown of this little guy, even though i've been using it for the last two years or so. Even though, as it turns out, i bought this a few months after starting this blog. Either way, i just put it up for sale (due to upgrading to the Scarlett 18i20 i inspected the other week). So i figured i might as well snap a few photos before it goes to its next owner (whomever that may be).
