The audio stage in the K1 is pretty simple and not much can go wrong. Assuming it's getting sufficient drive (no way to really check with just a DMM I don't think), it should work.
I would start with the "classics": 1. Check ALL your solder joints. Don't just look at them, reheat them. Don't add solder unless you forgot to solder it. 2. Recheck all the parts. There aren't very many. Make sure they are the right values. 3. Check all the voltages on U3 and U4. Good for additional evidence, but by themselves probably won't tell you much. 3. Try a different speaker. Or different headphones. My K1 seems to be very sensitive to speakers. I use an external speaker, but some 8 ohm speakers I have work great in the K1 and others with the same impedance don't have much output, yet they work on other rigs. I can't explain it, and I don't try. I just stuck with what worked! There's lots of other possibilities other than the audio stages themselves, but sometimes its good to know what's working to help you zero in on what's not. If none of this pans out, maybe someone else on here who is adept at troubleshooting with just a DMM can offer something. I gotta have at least my crappy little RS Signal Injector to troubleshoot.

It has very weak audio. The receiver seems to align, I can hear stns, relays click, filters wrk, LED's light properly, the display functions. trouble shooting is not my bag. No test equipment at all but a DMM. I just got back into ham radio after a pile of years. It is a new kit and is complete. I have looked at that thing so much my eyes are seening green, and everything seems to be correctly put together.
