There are two or three things that apply: 1. mini-banana female plug. This is like the standard banana plug but smaller. Try this page for some examples: http://www.oselectronics.com/ose_p111.htm Standard banana plugs are 4mm but you can use the springs used on 4mm plugs to fit a 3.2mm plug into a 4mm receptacle. The springs are hard to buy in small qty. You may have to buy standard plugs and 'transplant' the springs. This is tricky. 2. This search yields some results: http://www.google.com/search?hl=en&lr=&q=%221%2F8%22+inch+female+receptacle&btnG=Search There are several connectors whose 'female' parts take 3.2mm pins. Find the right one. F.ex. I think that one of them is the one used on PC power supplies for hard disk power. 3. Use a 4mm ferrule that can be crimped on a 3.2mm pin, and a banana plug receptacle (this sounds gross - the words). 4. Use a 3.5mm mini-PL (headphone/mic) receptacle, using only the ground pins to connect. hope this helps, Peter P. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
