[sdiy] Miniwave question

FInally bought and built a miniwave, then got sidetracked building a dedicated
VCO to drive it.  So I now have a nice stable 10v p-p sawtooth.  I'm going
to ignore one problem I'm having ( bottom half of waveforms missing when
switch set to 10v, but available when in +-5 mode ) as I may have a switch
wiring issue...  I'm curious about a glitch on the waveform.

I'm getting a tiny glitch on the rising edge of waveforms about halfway from
0 to peak.  Playing with trimmer 1 & 2 can minimize it but never quite make
it go away.  Can someone tell me if this is normal?  Its so touchy I swear
I'm going to switch those trimmers out for 10turns.

I need to make certain the miniwave is working as close to perfectly as
possible so I can debug the Minirom to make sure I built it right and more
importantly wired it right...
