Hi Greg!

I recommend the Johnson brand Banana Jacks from Digi-key.

www.digi-key.com

Example part numbers are

Gray Banana Jack = J359-ND
Yellow Banana Jack = J154-ND

(Download at the data sheet and catalog page for all the part numbers)


As far as Banana Cables... We offer a great selection of in-stock colors!

The Pomona "Model B" is The standard multi-stackable banana cable
of choice - used by most synthesists and mad scientists.

(All colors in the resistor color code are available)


Best Wishes!

Cynthia
