The Opus wasn't reading about 1/3 of the CDs that I had tried in it, so I replaced the laser in it tonight. Works great!

I assume that the values shown are mV? Also, when you say bias, I assume you mean offset? The first place I would start would be to measure the bias voltage across all of the 20R resistors, noting any variances. I would then do a comparison of the biasing circuits (consult the schematic) and go from there. It can be difficult to spot solder bridges on these, so checking resistance across all resistors (power off) might show you something. I know I had a resistor shorted that looked fine.

Yeah, that would work, but unfortunately they seem to have discontinued Fredrik. They do have some others that look suitable, if I can just find them in stock at one of the 2 Chicago Ikea stores. Thanks though!

Yeah... don't think so. I'll see if I can find something similar for less (and more obtainable in this area). Thanks!

Anyone know where to get a desk like that? Seems like that might be what I need for my work from home abode...

Happy Birthday Marc!

My wife is a big U2 fan. We've seen them live 4 times, the first two in 2001. Boy is one of our favorites from them.

Beth and I also... in person. Turned in our mail-in ballots to do so, against the president's wishes

Happy Birthday!

^ I didn't find mine to be that hard to work on, though I was pissed when I had to swap the SSD for the HD spots in order to keep it from buzzing (IIRC). But $60 for a 512Gb SSD would be worth it to avoid the fun.

Happy Birthday!

The "one"? The one I posted a link to? Or?

Yeah, I need to think about what exactly I want to do, i.e., where the music will be sourced from, and then how to get it from A to B. I think...

Happy Birthday!

Thinking about doing one of these, as I need SPDIF. Any thoughts? https://www.superbestaudiofriends.org/index.php?threads/dummies-guide-to-pi2aes-throw-away-your-pc-or-laptop.8878/

Happy Birthday!

Well, technically, it should be #team5pinxlr, as you could support both SE and balanced. Unfortunately, 4-pin seems to have become the standard.

I would terminate with a 4-pin XLR myself. You can always build a 4-pin XLR->1/4" phono adapter cable and use it with unbalanced amps, which is what I do with my DynaFET. I don't use portable amps anymore though, so the 4.4mm connector isn't useful for me. Plus, they are difficult to find, particularly a good chassis jack.

Happy Birthday Vicki!

Not sure Mikey. I'm not really up on any of the current cabling guys like Moon Audio (see some hits for these phones with Silver Dragon cables on them). It would be nice if AT said what they would or could do before you sent them in From the pic, it looks like it is just heatshrink that is splitting, but as you say, getting access to a free end to replace it is problematic unless you can remove the cable at the headphone end.

Now there is a HC approved overkill transformer! The two trimpots on the GRLV by the output terminals are for balancing out the output voltages.

The voltage selector switches I normally see used are C&K, mouser pn 611-V80212MS02Q. Other flavors available; this one is the straight PC mount version.

Maybe just put a voltage select switch right on the board as well, and only have 2 AC in (L/N)? EDIT: Also note that the 35VA/50VA trans use 1.3 mm pins, larger than the others.

Yikes! Glad I never looked into buying one then. I'd never read anything about them to this level of detail (such as the rails having to sequence correctly). That said, when it does work, how does it sound?
