Mine was waiting for me when I got home today.
Beautiful board. Same finish as the Reflektor-D I believe.
Now I'm waiting on some of the parts..
Very nice final board quality indeed. It worthed the wait.
And to you and yours! I've enjoyed reading your progress on this project very much.Is it okay to just wish everybody here a mary christmas ?
This is what i just did i guess...
Soo MARY CHRISTMAS ALL !
Jesper.
Happy listening in the new year.
Something from Shure maybe
Thank you and nice Christmas everybody.
Silence...
Guess there are some overheated solder-stations around the world right now?
Excited to hear/read when builder's are chiming in here!
Anyway, most i guess will be very very pleased with this pre. -Especially the 3D spreading/wide soundstage (dual mono makes a different here). Mine pre. has many hour's now of playing... everything is stable, and nice warm.
Can't we all agree that this is the real spirit of diy? ... waiting for something to test/listning to! -Something we build ourself.
Good luck everybody here.

Why one LED is off? Because green the package is giving enough Vf with 9?
Yes, with 10 led i get 18.7V - 18.8v, witg 9 led i get 17v. I am using Bf245a with 5.4ma idss, 1 ohm rd, i get id 4.8 ma.

Populating carefully
Remember that the boards are channel mirrored. Therefore double check the orientations of small semis especially to confirm they sit properly with the outlines on the silkscreen. Its already cautioned in the guide but today a builder PMed about what happens after he populated one Q5 in reverse and powered up seeing some smoke from it (Q5 on board is the BF256B JFET also mentioned as J3 in the theoretical). Answer is either half or whole the uPA will burn out, very probably one or two BC560s, and the BF256B itself. That will ruin your day, so be careful.

Mks2 100v
A little too big, I know. But they fit. Barely.
Cool Hikari1 ...
If i were you, i would place those two cap's at the opamp., underneth the pcb.
This gives you more space and easier handling of plugging in/out the opamp. during testing/finalizing.
Attached picture shows how little space there are around it.
Good luck!

Today i received and stuffed the boards.
Took me a only couple of hours to complete. If I had teabag' s kit it would be complete in even less time, but I had all the parts in my stash!
Will drill the sinks and test tomorrow.
This one will be powered with a single BIB for a secondary system, but I will make another one with dual DCSTB for my main one.

It also takes Shinkoh and Kiwame nicely I see. That is why I wanted roomy resistor places, so to can have options. What country of origin are the SMICAs? The dark green smaller resistors with color strips are German? Those R2s & R12s look like NOS carbon. I hope not compromised by years time carbon because those two values are high and self noise can be a factor.
Where did you source the input fets vgeorge ?
Would you care to share your supplier ?
Been looking through ebay and found strange results.... USA suppliers seem to offet those for 20 times higher cost then those coming from china.... do you believe I am now looking at fakes in ebay?
