Where are the calibration instructions?

There is nothing that I can find in the build docs or manual. I've been going off the 808 service manual but seems odd that they are not here (or I cant find them easily) especially since there are no labeled test points on the yotco

Also, not a single trimmer on my latest build is in range of the correct values. The build docs should be updated with the correct series resistors or at least a note indicating that part may need changing since those parts are difficult to get at

I had to read this forum very throughly to find the info required to calibrate my Yocto.
I had to change a resistor is the noise circuit and solder resistor in parallel with another in the cowbell oscillator section. I can't remeber which ones I changed and the values off the top of my head but can find out if you are interested.

Oh I know, this is my second one and I had to do the same thing on the 1st one that I built

What are you referring to? The 4 trimpot calibration settings are all in the build guide? Cowbell usually needs a resistor mod to ge a high enough pitch. What else do you need?

So you built 2 yoctos without the build guide?

never scrolled past the BOM
