Getting back on subject, I decided to try to evaluate the noise I was hearing. I hooked up one of my dynahi boards for the other channel and took a look at things on the scope. Both channels (FET/BJT) had some noise on them, so inconclusive. Since I don't have a function generator, I was using a portable CD player with a disc of hi quality test tones. When I unplugged the AC adapter, the noise diminished noticeably, but not completely gone. From what I recall, the dynahi was quiet when I was testing it. I'll need to recheck this with both channels to verify and make sure I'm not chasing my tail. Since my previous (4 years ago or whenever) testing had shown that the FET amp board went nuts with the crappy headphones I have in the shop for testing, I have had these plugged in most of the time. I replaced the feedback resistors with the original 1K/100R combo. Now things got interesting. Without the source plugged in (RCAs), I was getting a sine wave on the outputs (both boards!), at all volume positions other than all the way down (full attenuation). I did not determine what the frequency was, but strangely it wasn't really audible on the phones. I am theorizing that the FET board is oscillating and this is feeding back thru the PSU? Not sure how rational that is, but that is all I have to go on right now as there was no input plugged in, it remained with or without the headphones plugged in, and the only thing common besides the pot is the PSU. Next time I look at it I will verify that it is behaving consistently, and then go back to the 100K/10K feedback resistors. Maybe see what 10K/1K does as well. Any other suggestions? EDIT: I asked Todd to move this thread from the Casino to the DIY forum, and he obliged in doing so. If there are objections to this let him know (or me).2 points

Locking this thread, we're not currently seeking out donations. Also worth mentioning the the Amazon affiliate link is no longer valid, closed that out a few years ago now.2 points

Everything I have read says the Samsung "QLED" is just marketing bullshit to try to make people think it is different than their standard screen and more like an OLED.1 point

I will be there as usual. The event will be smaller than Canlanta but this will do for now. I can't wait to hang out with Brent again. Will Justin and Doug stop by again?1 point

Anybody else's HD800 earpads getting a little shiny and sticky? Mine are but just on the bottom-rear. They shed a little if I rub them there. I'm the second owner so I'm wondering if maybe the previous guy had a habit of slathering on Moose Mousse? Luckily I noticed that the pads are about $75 a pair which seems reasonable.1 point

Picked up the new Tux and donor package for tomorrow night's First Look for Charity at the Chicago Auto Show. Getting to look at all the new cars without all the riffraff sounds like an ideal way to spend a Friday evening.1 point

All right, I finished my first Dynalo Mk2 build. Photos: http://imgur.com/a/GSxFt. Have now listened to a few tracks, so far so good with the HD600, completely silent. However, when I connect a sensitive headphone, like a JH13 to it (which yes, I know, doesn't need this kind of amplification), it has a pretty loud hum. Grounding problem somewhere? Could it be isolated to the SE output? I don't have balanced cables for any sensitive equipment I have. I grounded the TRS sleeve to the chassis, is that wrong?1 point
