Discussion about the Korg PolySix synthesizer

I'm planning on building a new 367, one of Jed's boards as a replacement for my yukky one and grabbing all the parts I need ahead of time.  Can anyone let me know if there is an appropriate sub for this (ideally mouser) -> http://www.digikey.ca/scripts/DKSearch/dksus.dll?Detail&itemSeq=119392666&uq=634830080725755440

It is out of stock at Digi, and I don't use dip switches for my usual modular builds, so am not totally sure and don't want to buy the wrong thing that won't fit.  I'm going off Jed's BOM so the build goes easy.  I want my baby to work again, so using all the right parts.  Cheers,  Dave
