    Populated one of Victor T's (Dumbass) WPC89 Sound Boards. Running it in Whitewater. Nice winter project. Works great!

    Hey J
    Victor maintains great spreadsheets containing BOM and manufactures part #'s. PM him for the most current. https://pinside.com/pinball/forum/topic/dumbass-test-and-reproduction-pcbs?tu=dumbass

    did you happen to save your cart on mouser/digikey when you purchased the parts for this project?

    Hey JM
    I purchased the vast majority of components from Ed at GPE spread over multiple orders. Sorry, never made a spreadsheet.
    I remember buying a few obsolete IC's from UT Source. They were all fine. I may have been a little lucky because a few guys warned me about potential counterfeits.
    I purchased the Yamaha chips from arcadechips.com.
    Victor maintains a spreadsheet of components/ suppliers for all of his boards. Contact him for an up to date version.
    On a side note, do not use a Fujitsu 74LS138 for U26. It did not work properly in my WH2O. Use a TI.
    Good luck with your project. Victor makes wonderful boards.

    thank you for the follow up reply. I've ordered from ed in the past, but due to family issues he may not return and we may have seen the end of GPE

    I took your advice and have ordered a few of the components from arcadechips.com as well as some of the other hard to find components from pinball spare parts australia

    Hey JM
