Title: Missing capacitors mid-build
Post by: wenofyi on July 19, 2021, 06:16:49 PM

I'm part way through my MP573 build and unless I have missed something, it looks like I am three capacitors short.

Here is where I am currently: (https://lh3.googleusercontent.com/tGT5sbBEdXewBaW2dEiKptJHpslHOesxpVx5uIDQZ31lGIiAsHW_VLYEmn3I9JUzmIKh9vsHaleQA_FsQi0wMwh8ohrdIcNUGvJVaIjVArWQWO-XCg1ZL4VKmnBxJ2LgpTkPdMG0-nE9cK2qE_5VAOnIxdbxjDppiFBe7vugGQ4fwaG1Z_AxGWDiwRQ6RfZGnofzMM25hHION3jyRuPZcHjJwDtvh05GHPk_jPo-r99epK5Ce_Q2gaO-se4giIT7ckqinaW-b4Nenfko1RE25-h8DxcqJLktuVlg9uHBBO5y4MFMUrP6OMZZZm0qvdfQ_LF2U3CBKi8gFtQtAjHNWUWFSU6frNOqwNqrvqzUaZqcVR4lw7EWBc-uSkU6MyyPvaNdmj0CKmO4U-dv89Xz3ibOG01FYSG8SkDzeEMkKQCpXMdC1A8j8rvKaiuKat5rax0eU8EqP8Ot01s_cCbMcBnQdzTmIZpHenZiN5KkxGb9_QiUFyPEcHBnL89lgs-fsBO7fix-AvD-y8XOhE2fNZ864vKQTzU035-5FukIzr0mOgIT-plVNJYZLu7G3lFQqSrVrvTdiecPr2Igv-MhpWC8VivcOTHglWKPCKSWLbPoq79yJMrq3Io1Jvyn0Ae8y8JzMWR4Qn1omx6Jpreo6b5H9QNXlvKAC25mOgs-n_YhPLT0LfdrW37oOTTrP4-WQEjLtn6YFrGiKYpqOMyGqo4t9w=w1739-h978-no?authuser=1)


I need C10, C11 and C12. These are listed in the instructions as "large electrolytics", but on the parts list they correspond to the 330u-25V capacitors, which I already used some of in the "small electrolytic capacitors" step. According to the parts list, I should have 9 total of the 330u-25V capacitors, but I only have 6. I have soldered 4 and have 2 remaining, but it looks like I will be needing those 2 for the DI PCB. I am using documentation version 21.

Here are the remaining components in my capacitor bag:

Any guidance or suggestions would be greatly appreciated. Let me know if there is a way to be sent the missing capacitors.

Thanks!

This is probably an error from us, sorry for the inconvenience. We will send you the missing caps today.
