Kliche Mini voltages are not right!

I’ve built several of these and I’ve never had this big of an issue. The voltages on the ICs are way off. I’ve replaced resistors and a capacitor. I’ve checked all solder joints. I just don’t know what else to do. All 3 chips are socketed. I have Kliche that works next to it for comparison. Any help would be appreciated. I’ll try to post pics. I can’t seem to make that work either. Thanks.

Gotcha. You said 17.18 before.

If these measurements are with IC1 removed we need to find out what's happening to your VREF supply.

Make sure the values of R25 and R26 are correct, check the polarity of C22, and look for any solder splashes around there. Hopefully nothing is happening underneath the sockets.
