#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.

#54 Recycled backlight LED strip ambient lighting

What with winter drawing closer, and the days (as in daylight) getting shorter up here in the north, one tends to need to turn on the lights more and earlier than in summertime. And since i'm the gathering type, i figured it's about time i put some previously collected materials to (good?) use.

#53 JMicron JM20330-based mSATA to ZIF-ATA adapter power modding

A few years ago, in the quest for more storage space, power saving, weight reduction and eliminating sensitivity to shock, i decided to upgrade my old iPod Video (5.5G) from the stock 80GB hard-drive to a 256GB SSD, with the aid of an mSATA to ZIF-ATA adapter, and some mods to the "aftermarket" Rockbox firmware.

... Except that recently, for whatever reason, it's been kinda flaky, and ended up giving up altogether. To aid with stability, i had also performed some hardware mods on the power supply side of things (as well as on the iPod's mainboard). The rationale behind that, at least in part, was the source of the above-mentioned mods, so i'll need to transplant those to this newer one as well.

#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.

#51 Solar A2.7 & Fishman Fluence Keith Merrow & 5-way install

Local guitarist buddy time again (owner of the Fortin Grind and the Warwick bass amp featured here previously) - after taking several swings at it, he got fed up and let me have a go at installing a brand new set of Fishman Fluence Keith Merrow pickups into his Solar A2.7 guitar. Complete with some custom switching and whatnot, to take full advantage of the entire feature set the pickups offer.

#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.

#45 Pedal pandemonium, part one - Fortin Grind

A local guitarist friend of mine recently upgraded his rig to a Fractal AX8, and as such, a couple of his overdrive pedals got relegated to (mostly) sitting on a shelf. Knowing some of my interests, he offered to lend them to me, to have a look on the inside, out of sheer curiosity.

First on the chopping block (as it were), a Fortin Grind. 

#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).

#42 Presonus Audiobox 1818VSL - revisited and revived!

[Part one can be found right over here]

Through a mix of patience, persistence and good luck, i managed to get my grubby mits on another, fully functional Audiobox 1818VSL, for considerably less than the 1-2 pricey ones available on eBay in Europe.

#41 Focusrite Scarlett 18i20 (1st gen) teardown & repair(?)

A local friend bought this slightly battle-scarred Focusrite Scarlett 18i20 off a buddy of his. The reported issue was some random / intermittent noise affecting only the inputs. Time will tell if that was conveyed to me accurately, or if it's a more global issue. First thing's first though - having a wee little look-see on the inside.

#40 Fake "Beats" Bluetooth speaker teardown & mod

I got this handed in by a local friend the other day. It was apparently bought in Singapore a good few years ago, hasn't been used in quite a while, and i guess(?) the charging cable (slightly less usual mini-USB) got misplaced or something.

#39 M-Audio Profire 2626 teardown and repair

Ebay strikes again - this time, a pretty damn cheap (to acquire) M-Audio Profire 2626 Firewire audio interface. I maintain it's still the cheapest way, to this day, to get 24 inputs and outputs to and from a computer. Most other 1U (rackmount) interfaces will give you 8 mic preamps but only one bank of ADAT. The ones with two sets of ADAT I/O will cost you a pretty penny, though.

Either way, this was sold as "not detected by the computer", so my bet's on the Firewire chip being toast, "as usual". Can you see a pattern emerging here?

#38 Focusrite Scarlett 18i8 (1st gen) teardown

Yet another "sold as faulty" eBay catch - a nice little(?) Focusrite Scarlett 18i8 USB audio interface. Which turned out to actually have nothing at all wrong with it.

Admittedly, i went against the first commandment of teardowns (ie. "Don't turn it on; take it apaaaah't!.."), but only because it was the first troubleshooting step, and it used the same drivers as my Scarlett 18i6 "daily driver".

#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.
