Tech Help - Projects Page / total recall... signal at 7 but hi pitch squeel at 3/4 - no delay edit: solved

edit: solved
hello,
before you ask: yes, I prob bit off more than I can chew. not a complete novice as I've built quite a bit but def finding this hard since I can't see the traces.
I know I can't ask anyone to solve it for me... just sort of stuck and was hoping someone might give me an idea of what to check next.
i used the mouser cart for parts and seemed to have all I needed... did have some extra 24k but I may have ordered extra as it seems to be a common value.
followed the build instructions and checked the dc jack, and regulator before I ever populated chips.
what I've checked so far...
dbl checked that the mn3005 is oriented correctly to the solder mask.
-15.14 at regulator (-21.7 coming in)
-15.14 at pin 5 of ic6 -6.8 at pin 3/4
dbl checked all electro orientation
dbl checked d1 orientation
signal checked leading up to pin 7 of ic6... plenty of clean signal at pin 7 with level set to 40%
i have a couple of extra xvive mn3005 from smallbear, swapped out chips to check... sm result. unless I got a couple of bad chips... but I'm not sure what the effect is when you have a bad chip... do you get a high pitched signal at pin 3/4? i had initially worn a shock band while installing... ensured I grounded myself when swapping.
any help would be appreciated.
