Not to mention getting all of those pesky and conductive metal filings from rethreading lodged between IC legs and wedged into transformer windings. FUN times!

Not to worry, that will only reduce output impedance. Right?

Hi Guys, can someone give me a little help here? im doing a diy mod in a "power manager rc5" to control my Schiit products and connect them more easily.
I need connect a 20ma Led in the panel (works between 2.6 and 3.6V) directly to 220V AC so this schematic is right?
thanks a lot

The connections look correct, but I don't think you want to hold those metal mains connections in your hand when you test it.

LOL sure! And you'll just get so much more current at no extra cost - it's a win-win situation! I just had this exact scenario play out at work today. We're trying a new emission indicator LED design and forgot the current limiting resistor, or shall I say assumed it was in the upstream circuitry. Replaced the blown LED to find out that it was on all the time now. That was because I also blew the FET that was the switcher. Live and learn.

Thanks for the reply, and dont worry i will cover everything with eletric tape!

Do we have any European Yggy owners here? If yes, who did you order your unison boards from? Neither electromod nor sonority seem to have them in stock.

Ordered it from Schiit USA/ Arrived within a week.

Did you have to pay additional customs fee?

As expected 21% VAT + customs handling fee. Total price to my doorstep just over € 200,00. Worth every cent.

I am on the fence as to whether I should install unison myself (with some help from my brother) or ship the dac in and let Schiit do all the work. All this screw talk is making me nervous lol.

Afraid to screw it up?

I just finished the Unison USB upgrade to my Yggdrasil. Took under an hour. Listening now via JRiver 25 on Windows 10.

Me too. Very easy job if you have ever opened any audio electronics components.

OSX and Roon recognized Unison right away.

Ironically, my server is the only MAC in my house. I don't like Apple stuff, but OSX has a lot of features that make a home server very easy.

Tube question - what causes a tube or tubes that have been dead silent for weeks/months (and should have many thousands of hours of life left), to suddenly start making scratchy/static-ky sounds? And what's to be done? Should I take them out of my Freya +, and blow into the sockets? Clean the tube's pins with isopropyl? Any insights would be most appreciated!

@leonthebumme

Oxidation on the pins or debris inside the socket from inserting/removing many tubes is a possibility. Cleaning technique depends upon how much crud is on the pins. If it's severe you can use steel wool or high grit sand paper to get back down to bright metal, but it's very important to clean and inspect afterwards to make sure there aren't stands of steel wool or other junk left on the pins when you're done. After that a scrub of the pins with deoxit followed by a cleaning pass with alcohol (you don't want the deoxit in your sockets). I do this with all NOS tubes I buy.

Less likely possibilities include the tube beginning to develop a short between heater and cathode, and the beginnings of continuity issues in one of the pins from repeated insertion/removal into a socket. Reflowing the solder at the ends of the pins can sometimes help with the latter. The former is only really discoverable with a good tube tester and if that's what is going on then the tube should go in the trash.
