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.
Can't tell you anything without seeing your full circuit voltages.
roger that... will do.
total recall

last one is ic9 not ic7 repeat and is a 4558... missed that
ic6 was out of whack from ic7 as I had adjusted the trimmer in a wide sweep trying to see if I could dial out the high pitch sqeel... adjusted to the middle and got

once again proving that it is better to be lucky than skilled... I managed to figure it out on my own... thanks to those who considered helping me anyway. Just hit it with a hammer a few times and voilla. nice sounding build. much smaller than my reg memory man. probably could benefit from a second pass on the bias but good enough for today.

When in doubt, give it a clout ;)
Well i'm glad you got it sorted in the mean time!
is there a restriction on new guys posting images? got the img tags in there... is there something I'm missing?
