The module needs two good capacitos for VCO and LFO timing. There no polystyrene caps in Mouser. But there are mica caps. They are very good but 10n a bit expensive and too high (about 20mm) but I think it's possible to mount it with some bent.

Where to buy?
I included into Mouser shopping cart 8 Kobiconn jacks. But they need to solder a leg for ground connection.
