Ok, I bit. Damn you, ebay!
-
My preferred suppliers would be Farnell and Elfa Distrelec but none of them seem to carry it.
As I said two of the local electronics stores have them but I have a bad feeling that they get them from ebay. Some of the local diy-ers who bought transistors from them got fakes.
In any case I'm in progress of doing a full transistor test on my Dynalo.
-
No, he's still selling. 8$ a pop.
-
For the Dynalo circuit would there be any meaningful difference between GR and YTA designations?
-
For $3, you aren't risking much.
I'm pretty sure this is how this business works. If shipping won't be too long then I'll bite.
Edit: Damn, shipping is more than two weeks. I'll pass. One of the local guys had bad luck with this seller.
-
Is this too good to be true?
My local suppliers are almost out of these transistors. And the ones I got so far from them seem to be somewhat unstable.
-
Luckily only the output stage seems dead. Some desoldering braid and two dozen BJT's should do the trick. Maybe I'll swap out the bypass electrolytics as well.
What's worse I actually heard how the amp sounded. Hence the rush that lead to this.
-
I reversed wired the PSU to my Dynalo.
-
Darn it! I have my eyes on an ampless Pico DAC and now it seems that it just won't cut it.
-
-
Are you using the Pico as a DAC only or can it be used as an amp as well (provided it's the amp version)?

On a side note- was I the only one who was disappointed by Sigur Ros Valtari album?
-
Dumplings stuffed with smoked pork. I had higher hopes to be honest. Tasted like french kissing with ladies who like to smoke a lot.
-
Surely you used a powered USB for the Pico, yes?
In any case this is great! I'm eyeing the S3 as my next phone.
-
I guess that's the price of doing these rational interventions.
-
They designed the HD800 and HD650 to dry hump, and the next flagship will just be snake oil soaked HD25s.
Please elaborate. And don't forget to add for how long and on what equipment have you heard the said headphones.
-
That actually explains a lot.

What about IEM's for added bass extension?
-
I'd only buy a Samsung tablet or a smartphone with tubes.
-
I used to listen to Deftones when I was 18 or so. It was the hip band that's alternative to Korn, SOAD and other nu-metal players of that time.
-
The logistics behind all this... Unbelievable.
-
Ok, I'll try to apply the flux more often.
Scratch the switch question. I might have an idea how to do an amp with a switch that's beyond awesome (yet slightly impractical and most probably toxic).
-
A few beginner questions-
1. Is there any advantage in using dual pole mains switches?
2. When soldering through hole parts onto a both-sides-plated PCB is it important to have neat concave solder spots on both sides?
3. If some parts happen to stand quite high from the PCB, should I make an effort to push them as close to the plate as possible? Some of my Dynalo resistors are standing unevenly and frankly I hate how that looks. Common sense tells me that doing so may minimize signal path.

Adam seems to be the Emotiva this side of the Atlantic. I was torn initially between the Quad 12L active and one of them 5'' Adams (both being sold at a similar pricepoint) but somehow I shifted towards the former. My sound preferences are best characterized by the HD650, therefore I'm a bit afraid of the monitor sound being sibilant and whatnot.

Yeah, only the really crappy solid state designs have output impedance on the high side. My local electronics guys have a few interesting ideas about building an amp with switchable outputs- one super clean solid state with suoerb damping factor, other with higher Zout and a third with a simple tube output for even order harmonics.
P.S. I recently took a look at some Russian DIY designs and I must say that these guys are pretty damn advanced. Especially the DAC's.
