This is my finished Doppelgänger Doppelgänger ;)
First off, hats off to Lacesensor and alanp for the board layout and all the work to make this happen. Secondly, put your hands together for all of the little helpers I had debugging the build after having weird oscillation and noise issues. Turns out I had the dry out touch the regular out despite insulating tape (there was a microscopic rip in the tape...).
Anyways, it sounds great now, although I haven't gotten around to fully testing it yet. This is one of the most complex builds on my list yet. Lots to learn from the build since there are lots and lots of board mounted parts to align (drilling was nerve wrecking despite test drilling on wood) and the amount of jacks included. Also, applying a decal of that size is not easy at all.
'Nough said, here's some pics:

great work, Felix! glad you have it all sorted out!
YO.....
Where's the audio? Lets hear this bad boy! ;D
Nice build! Simple and elegant.
Great job getting this working! It looks awesome, I hope you really enjoy it.
Excellent! Your persistence paid off big time.
That is so beautiful!
What finish did you use?
Is it decals and epoxy?
Looks really super clean.
Awesome build, I was working on mine this last weekend and can't wait to finish it.

its envirotex. i didnt have the guts to try it with 9mm pots so its just label on mine. this looks spiffy though, im wondering whether theres any play in the pots from being without a nut?
nice! love that gloss and the graphics
That looks awesome!
WOW!! That looks so good! Can't wait to hear it.
Damn, that's hot. Love the color, graphic and knobs - all works so well together. Not to mention the inside is unbelievably sharp. Great work!
Great looking build. I dig the details like lining up all the switch nuts. Well done.
Hi
thanks for posting this. Its extremely gratifying to see these "in the wild" and know that people can follow the build docs etc. Enjoy what is surely one of the best analog optical phase shifters.

Great build, Felix!
Me likey :) (but then I'm biased.) I really like the city-scape photo!
Thanks guys, your comments and feedback are very much appreciated.

So, Cody asked for my drilling template, so I'll just as well post it here.
ATTENTION: I used a 1590XX enclosure. If you use a different enclosure, make sure that the relative positions of the drill positions stay the same, eg. by just printing it in the 1590XX size and centering the graphics on your enclosure. I had a small problem with my square switch (I ended up drilling 7mm instead of 6), so make sure it fits! I could have just been me not center punching accurately. In my enclosure the open style jacks were no problem to fit next to the PCB - the closed ones were a really tight fit, just make sure to consider the height of the board.
I used Gimp to make the layout, don't be afraid of the billions of helping lines I used to get all the positions in place. I also included a png and a pdf version. Hope it works.
As always: measure first, remeasure, then drill! Best of luck!

Thanks so much, I don't think I have ever stressed this much on a enclosure. I just hate to waste a enclosure due to a miss drill. I seem to always have problems with using open ended 1/4" jacks that are close to PCBs and switches. Thanks again for sharing it.
Cody
the template does not include the jacks unfortunately. I just put them were the labels are on the front cover and put them as close to the bottom of the enclosure as possible to make them go over the pcb. since you can rotate the open frame jacks, I think you should be fine.
So is there one deeper?
If you think the Doppelganger is a bit hairy to drill, wait till you try out the Rissole. I deliberately overdrilled on that one.
Great work at something that I will never attempt to do I guess. Hard work pays dividends. Cheers
