It's unlikely anything else got destroyed, but not impossible of course...  It would either be a chip like an opamp (if you shorted the rail by shorting the chip) or possibly the corresponding 7815 for the +15V.  But it's unlikely as an opamp or the DAC would go up in smoke before the regulator.  79 series are negative voltage, so a 7915 is -15V.  I'd get both a matching 7815 and 7915 (TO-252 package it looks like) at the same time.  They're under a dollar each from DigiKey.  Any electronics supplier should have them as 78 and 79 series linear regulators are completely and totally ubiquitous.  The 79M15 is rated to 500mA and costs about $.41 in single quantities.  For $.81 you can get a 7915 which will do up to 1A before going nonlinear (voltage drop and overheating).  The only annoyance is TO-252 is a surface mount package.  Don't get the 79L15 as it's only rated to 100mA.  In the early 80s (I got my EE degree in 84) we used these to produce RS-232 voltages, before those handy MAX232's showed up.  My bank PIN code was 1488 for a number of years, any EE of that era will get this.

Downloaded a couple of 24/88200 albums from hdtracks and I hear what sounds like little pops/skips every now and then. Also have some 24/96 files that play perfect. Using USB audio player pro for android. Anyone notice this issue? Not sure if its the Aune or the player. Any help would be appreciated. Thanks

Could it be a buffering issue? The player allows you to change buffer sizes. Never had to mess with these before, so kind of in the dark here. Thanks
Marc

 

[SirMarc]

OK, so I increase the buffer size from 100ms to 200ms and it doesn't do it anymore. Is there an optimal buffer size I should use? Thanks
Marc

My Aune doesn't play 24/88 (I have to resample in foobar).

Maybe USB audio pro upsamples it to 96? It shows the aune at 96, and the file in red at 88.2. Don't know, but increasing the buffer size from 100ms to 200ms seems to have fixed it. On a side note for whoever has an android phone with a ton of music on it, get an otg cable and use the phone. I find it way more convenient than using the laptop for kicking back on the couch for serious listening. Most newer android phones can use a 128 gig card, so you can get plenty of flacs on there.

Or you can use your Clip Zip to do the same thing.....♫♫

Thanks for the tips sandab. I managed to desolder and pull the old regulator chip today. There's an electronics shop here open Monday to get a replacement. Should be interesting to see if I can replace it... It's a pretty tight job. Wish me luck

I wish you luck! Monday my Aune T1 will be in my hands!

You can do that with an android phone?! I thought only DACs of iDevices could be bypassed. Will this work on any USB DAC?

 

[SirMarc]

Yes sir! There's an app called USB audio player pro, think its 10 bucks, but worth it, that does bit perfect streaming to a dac. Most newer androids are plug and play, but the HTC one m8 needs this app to bypass boomsound.

Fixed the static. Both bad usb cord and outlet. I was really worried.

Here's something interesting and sort of related to the T1.
 
My Olimex USB Isolator started to emit a LOT of smoke when I turned on the T1!!!!
 
I even shot of video of it. Right before I turned it off. I'll need to RMA it but I'm wondering if ;
 
1) It'd be worth it considering Olimex is in Europe.
2) If they'd even bother to honor a warranty on a small product like this.
 
It costs roughly 60$ and fixed the issue I was having previously. Sure hope they're not all like this.

Anyone looking for some NOS Philips SQ E88CC Holland gold pins?
