I'm refurbishing an old Apple II Power Supply made by Astec. It's working now, but I damaged the connectors which connect the Live and Neutral wires to the Power Supply PCB. On the PCB are two posts, each about 1cm tall, and maybe 2mm in diameter, with a "bullet connector" like shape. The wires have what looks like simple cylinders which plug onto the PCB posts.

I can't find any reference to, or even images of such connectors using Google. Does anyone know what they are? I guess they might be proprietary to Astec, and possibly even obsolete, but before I do anything drastic, I'd like to try to replace them with the right ones.

Here you can see the connector in the foreground, beside the fuse:

  • \$\begingroup\$ Kind of reminds me of this guy, but it is not a PCB component... How large is the hole on the one you have? \$\endgroup\$

You are likely looking for bullet or barrel connectors. Try going to digikey in the terminals sub section : http://www.digikey.com/product-search/en/connectors-interconnects/terminals-barrel-bullet-connectors/1442843?k=bullet

Another source would be http://www.digikey.com/product-search/en/connectors-interconnects/rectangular-connectors-contacts/1442670?stock=1

These would be crimp on (can be soldered) to wire, providing you a single barrel like connection. You will need to use the search functionality to sort out what you are looking for specifically. I would use molex for the manufacturer as they make an assortment of female connections for power, such as what you would see on vintage RC car battery packs. Just search google images for "rc battery pack connectors".
