Since relatively recently acquiring the MOTU 8M, once i got around to swapping it out for the 896 mk3 in my recording rack, i figured it might be worth doing a quick teardown of the latter, before i sell it off. I've done a really brief one over on the BadCaps.net forums when i first bought it, but it deserves some higher-res photos and a more detailed documentation of its guts. Do keep in mind that it got re-capped as soon as i got my hands on (or into?) it, so the electrolytics are not stock. But
without further ado...

#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.

#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.

#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.

#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.

#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.
