Wanted - pre-power section connector links for Marantz 4240

[Doomlord_uk]

Hi, I have a Marantz 4240 I want to work on. It's one I got off eBay ages ago and stored away as I didn't have time for it (I just grabbed it coz I could ). Anyway, after eventually pulling it out and trying it, I didn't get much useful performance so it has a few issues. One being the volume control didn't adjust the volume. Anyway, I spotted one thing it's missing - those little U-shaped links for connecting the pre-out and power-in RCA connectors on the back.

Can anyone sort me out with a couple? Or point me towards where to go for some? I'm not even really sure what they are properly called, so googling hasn't helped so far... Hopefully they aren't expensive! I can PP a few dollars to someone who can help me out to cover shipping and a bit extra. Let me know if you can help - thanks!
