I built the same kit on 40m band just recently and had a very similar problem.
Yes, there is a checklist of voltage readings to measure using a DVM on pages 133 and 134. I found a cold solder joint on IC10 (ground pin) that fixed the problem I had.
Please read and carefully heed the instructions on pages 132 and do not attempt to probe the surface mount IC pins directly.
Hold off on the oscilloscope.
