July 23, 200916 yr Below is -=Germania=-'s handy work for your viewing pleasure. The unit is an opus dac with usb receiver and a 41hz amp 6 t-amp. The big pictures are of the power supply to the amp that is now making a ticking sound. The front LED is no longer being powered. There is also a low hum from the unit, but I can't tell which board it is coming from. I have a multimeter and soldering iron, so if theres something uncomplicated to try, I am game. I built my power conditioner, so I'm not a total noob, but I never learned how to read circuits. Biggie.
July 23, 200916 yr Biggie, you should really consider asking her for a full refund after seing those pics. The wiring is piss poor, the layout isn't much better. Really bad is that I can't see a fuse for the DAC power supply and there are a few airwired capacitors in that medical power supply which could mean trouble in the future... Overall workmanship is terrible and you shouldn't be happy with that!
July 23, 200916 yr Author I ordered it based on this thread, which I posted on here, and her good feedback: http://www.head-case.org/forums/audio-gear-sale/4902-wtb-diy-dac-amp.html If there were horror stories before me, they weren't documented on head-fi as far as I can tell. Biggie.
July 23, 200916 yr Get a refund now, not later, now. If you choose any other route you're nuts. I can't believe that power supply is mounted on what looks like a plastic sheet. epic And holy shit, are those McCallisteresque drill chatter marks I see too?!?!? Christ.
July 23, 200916 yr Its the sort of thing you could forgive for a total noob doing their first project...... but abso-freaking-lutely unacceptable for somebody selling it for profit And holy shit, are those McCallisteresque drill chatter marks I see too?!?!? Christ. Oh shit, I didn't see that. Awesome
July 23, 200916 yr Listen to the man ^^. Just send it back and get a full refund. Ask her to deal with the insurance and tell her that she can pocket whatever she gets out of it (not happening seriously). Insist upon a refund.

I can't believe that power supply is mounted on what looks like a plastic sheet. epic damn!!!..hadn't noticed that Nate..wow.. that is fantastic FAIL!! The USB connector is on the inside of the case too..
July 23, 200916 yr I'm digging how she got all the screws installed....oh wait never mind. Also like the power supply hooked directly to the power LED. Sweet. And cool beans. It does look like the IEC is the fused type so I think it's safe in that regards.
July 23, 200916 yr Biggie, you need to post those pictures in the thread over there. This isn't about public shaming, but about accountability. Based on a series of unbelievably lengthy pms, mostly unrelated to your issue, she has zero sense of it until it's hammered into her skull multiple times. She's is going to fight as long as she can to blame this on shipping, and unless she's more or less cornered into accepting responsibility, you won't get your refund.

Biggie. Damn aardvark bag's post was a joke \
July 23, 200916 yr Holy fuck, is that power supply screwed directly to the chassis with a piece of goddamn PACKING TAPE under it?!?!
July 23, 200916 yr Demand an immediate refund, no conditional, not 'if shit happens'. Post it publicly on Head-fi. That is inexcusable. Without knowing a forking thing, you could have done better yourself, just asking for guidance from folks on this thread. And, no one, I mean no one can wander drill marks like Peter. And, no one can jerk a refund claim around for 9 months like Peter. Don't let -=Stacy=- be like Peter.
July 23, 200916 yr Ok yeah, Biggie I would recommend that you not turn the amp on again until that PSU board is properly mounted on stand-offs. Actually, unless you can tell whether the power switch is on the live or neutral wire, probably best to leave it unplugged as well. That board is wired directly to 120V, and the chassis is not earth grounded, so if the wire that isn't switched happens to be the live one, the switch won't mean a damn thing if it the board shorts out against the chassis. I also see an exposed solder joint on the mains wiring between the two PSUs.
July 23, 200916 yr Biggie, that isnt a 41hz amp6, that is a prebuilt TA2020 amplifier that some guy on DIYaudio sells for 20 euros: diyAudio Forums - New ta2020 pcb'S - Page 1
July 23, 200916 yr Is it just me or is the wire that's going from the tranny to the board nicked? From the first pic it looks like it's nicked just up and to the right of the board. Other pics seem to suggest the same thing it's hard to tell with the focus.
July 23, 200916 yr Not nicked, rather it looks like a solder joint to repair the wire. With no heatshrink on it.
July 23, 200916 yr Exposed solder joint on a transformer wire? No chassis safety ground? That certainly sounds safe. I can't see the pictures from work, but I'm somewhat afraid of seeing what the pictures look like.
