Wrapped up the SMDs on the main board this morning. Those little diodes are a hoot. They don't like to lay flat with the hot air machine, so you have to be creative with the tweezers, your magnifier, and the blower. An extra hand or two would have been handy.

Hi,
thank you very much for your feedback!
Your controller don’t need the update if you assemble the two external resistors.
If you are still interested in it, you are welcome to send me a PM.
@Chris: I
your pictures and build guide. What are you planning for 7x15 voltage regulators?
I recommend to use types like UWB2, Belleson, Sellarz...
My favorite are
SIGMA78 Low Noise LDO Voltage Regulator +15V - Audiophonics
SIGMA79 Low Noise LDO Voltage Regulator -15V - Audiophonics

Thank you very much! I appreciate it a lot. Others' building experiences have been very helpful to me, so I hope to return the favor. 🙂
I hadn't thought about anything special for the regulators, actually. I just picked up a set of ST Micro L7815CV/L7915CV from the usual electronics suppliers. I'll certainly give those other two a look. The quieter the better, no doubt!
REG40 (LD1117S50) was a hard one for me to find in stock. Ended up finding them at Arrow who had thousands of them where everyone else were on forever backorder. Hurray for Octopart.
I think I'm going to stick with what I have for the moment. At $0.56US and $0.63US per piece, it's worth it to at least give them a try before jumping into the $12US devices. 🙂
Appreciate the offer! If I find that they're noisy, I will certainly reach out.

That doesn't work either unfortunately. I'm starting to think they do something funny at the border when shipping things to the UK....
@Chris In Milwaukee,
didn't read all posts but one question, will build balanced?
If yes the lower main boards didn't need all parts ... if not you are one the right way. 🙂

Hi Carsten,
Yes, I am building balanced. Which parts aren’t needed? Presume power supply? If so, I have a third board and will build as needed and use the other in a single-ended project.
Thanks for the catch!

Ah yes, I see that now. I didn’t make that connection until now. Now I get it. Is the power supply board expected to be in the middle layer, or can it be on the bottom?
Thank you for the reference. I’ll get that third board put together the right way. I was planning to use that extra board for another project. So I’m already ahead of the game. 😀

After thinking about my question a bit, the power supply is probably better in the middle layer (top main board) since it will cool better there.
Of course, you need only a few parts on the second board.
From top to down .... (hopefully)
Sorry for the ranking of the pics. Please show to second pic, that ist only what you need for balanced. All comes from the "main" main board and all ist parallel.
[EDIT] not my day :-(
