Thanks for pointing out my oversight TuneBlade, I should have gone back and looked at your support documents. :)  That seems to have fixed the problem.  Thanks!

​Since I can hear a big difference between the head out from the laptop and streamer I think this is some other issue?  Wouldn't I hear it from both sources?   It's not a small loss in quality, the stream is really unlistenable.

Someone gave me an Excelvan DLNA music streamer a while back and I'm getting around to getting everything working.  Android and Apple were straight forward and simple enough and for Win 10 on my laptop I downloaded TuneBlade to get the stream working. http://tuneblade.com/ Problem is, iPhone...

Thanks Roseval, I was unaware of this issue with WAV and that helps quite a bit.   Since I don't need the best in quality or a ton of music on my phone to listen in the car, I think I'll just rip another small compressed library for iTunes and be done.  I'll convert the existing WAV files to...

I had burned quite a few CD's to WAV , with iTunes, but have recently downloaded Foobar. Apparently, the metadata tag between the two are not compatible. When I open my library in Foobar I get "?" under the album title and I just get a giant list of tracks under a single folder. I tried to...

I built 2 and I had a minor hiss problem in one of them that had the transformer in the same enclosure. A bit of a twist to the transformer fixed it up. I have also noticed that the tubes pick up a bit of noise from ground when I put the top cover on the case. The tubes sticking out of the case...

Click on the part number and the "bundle diameter range" is in the specs. Here's a copy paste of what I see. Part Number: 9284K315 $2.52 Each Type Expandable Mesh Expandable Mesh Type Standard Material Polyester Flame Retardant? No Construction Braided Inside Diameter 1/8" Wall...

The nominal ID of the sleeving is 1/8". It will contract a bit to fit nice on a 1/16" cable when you pull it tight. Specs read for a 1/16" to 1/4" cable bundle, I think that will be the closest you'll find if not spot on.

Try McMaster Carr for expandable sleeving if you're in the states. It's about $2.50 for 10' of what you need. I can't direct link to the product so here's the McMaster link. McMaster-Carr And here's the part #. 9284K412 Or just search on sleeving to see their other options. They have...

What do you read for an input voltage? (From the input connector on the board) What's voltage at TL+/- and TB? [edit] Never mind, I lack reading comprehension skills. Looks like Runeight cleared it up.

Well, after listening to the amp for a couple days I’m finding it is very susceptible to noise. I haven’t checked with an o’scope yet but I must have quite a bit of noise on some of my outlets at home, hiss is quite bad at some outlets and better at others. I also found that without the top...

Yeah guys, the amp is working nice now. This is my first headphone amp and I don't have a decent set of headphones yet but, so far it makes my cheap (relatively) in ear plugs sound like I haven't heard them sound before. I can hopefully borrow a few sets of phones from friends in the next...

I found the bad trace on the board the other day but I still seem to be having a slight issue with the left channel. I'm getting a wild DC voltage swing at R10 from -5 to +5VDC. It does settle down and act nice when it warms up but, on rare occasion at power up it can take 2-3 minutes to...

I found it! Looks like someone may have left a hair on the fab during etch. I took a picture to show you guys what I found, perhaps it will help one of you out in the future. Check out the bridge between the traces at the solder pad for R10L (Q5L in lower right of frame). I cleaned a bit of...

Well this problem has got me chasing my tail. I took some measurements and found I was short between pins 1 and 2 (collector and emitter) of Q6 so I pulled it out. To make a long story short I currently have Q5, Q6, C1 and the OP amp off the board yet I still read a short (0 ohms) between...

I have double checked for any shorts, bridges or bad joints and all looks good. I'm reading 7.2V at the base of the BC550C (Q5), 14.95V at the base of the BD139 (Q6) and -15V at the OP134 output. I appreciate the help guys.

Hi folks, Another new guy here building the Soha. I've been following this thread from the start and finally decided to build but, I have a bit of a hangup with the epsilon circuit. The relay isn't kicking on. I think my problem is in the left channel. I have set my voltage across R10(R&L)...
