One more thing I forgot to mention.   In the DAC test, it seems that the pots that are being measured are the Filter Cutoff and the Effects Intensity, so it would be interesting to know if those two affect the average DC level at the DATA pin using the test I mentioned earlier.

As for the DAC, in the KLM-267 board I have its a MC1408.

I also received a new DAC chip from Newark Canada (that's where I am), and it's the DAC08-CPZ from Jed's KLM-367 clone board parts list.

One thing I noticed though is that in the clone board IC-33's pins 7 & 8 are connected, whereas in the original KLM-367, pin 8 is floating.
