I haven't had any problems.
4 Tap DC Converter/Isolator

Tried that on my first build... 2x111, 1x222 and 1x333. Changed it to 4x111, from my understanding, the regulator is the bottleneck. Could not save the two converters I had to take out.Have you used these yet? Just wondered how you got on? Is 333mA too much I was wondering? Can you ever have too much

Some redditor maintains that running at 10v-11v might be functional but it will eventually mess pedals up, particularly with digital.
Legit or ignorant? (because I trust the people of this forum much more than a rando redditor)

Out of curiosity, have you measured the output with a load connected?
XP Power has switched up their catalog quite a bit over the past few months, but they do offer regulated versions of their DC/DC converters.
Any digital circuit should have a voltage regulator (or multiple) that can handle a 1-2V variation in supply voltage. I'm not going to claim it's ideal, but I also do not believe you are going to have a catastrophic failure.
We could add voltage regulators to each output but idle current will increase significantly... We could counter that by removing the "Universal Input Voltage" ability and just power the thing from a normal 9VDC power supply like any sane person would do.
Is anyone powering this with other than 9V or 12V DC? I would imagine that percentage is small.

Well.... yeah, you'll need a regulator on the input then....

@Robert, just to note there is an inconsistency in the docs and board print. One part of the docs specify 50v power rating for C1 and C6, board print and the other part of the docs only for C6. Not a huge thing, but it did make me paranoid enough to desolder a second 50v rated 100uf from another pedal.

Ahh thanks for the heads up. C6 is the only capacitor that should have been listed at 50V, and only if you're powering it at a voltage that would require it.
I think I went with 50V all the way across, just because.
Corrected.
