Well, I actually did increase the input voltage so that the Oscillator Board saw 5 VDC instead of about 2.5 VDC and it made little difference in the output amplitude, perhaps 10% or less. I am sorry, but my 'scientific method' has not regenerated itself sufficiently to drive me to make careful notes.

The VCC seems way too low. Interestingly, noone else seems to think so, or did not notice it.
