content: I've got a TTi PL310 power supply here and it's missing one of the shorting bars between the output and sense binding posts. This isn't idea as occasionally the bit of wire I have wedged in it falls out. Is there a source for these in the UK. I couldn't find anything on Farnell / RS. TBH I don't know if they're even called shorting bars or not.

content: Still expensive. Currently it's a bit of metal with two slots in it. TBH at this rate I think I'll just grab some copper shim off ebay and cut one out with some snips...

content: When you say " the bit of wire I have wedged in"... have you tried using some decent thickness wire (as in solid core mains twin and earth) and putting 90' bends in it to go through the cross holes in the binding posts? That's pretty secure and very cheap!

content: That's actually what I've got wedged in it at the moment but it's annoying me as I occasionally need to use it as a proper binding post with a bit of wire and it's hard getting two things in one post that are round. Plus it falls out periodically.

content: There's a type of bus bar that's similar to that, may be worth tracking down an electrical wholesaler and asking, if they've offcuts they may even just give you some of it if it's not cheap enough to buy a strip.It wouldn't be that difficult to make out of a piece of brass from a model shop though.

content: Drop them an e-mail using the address on the website (http://www.aimtti.com/webform/contact-aim-tti) and they may well just post one out to you.Don't use the webform, they don't seem to act on those, but an e-mail was replied to within a day when I got in touch recently for a firmware file.

content: I recently got some from Digi Key in the US - Pomona Electronics part number 4115; DK part number 501-1505-ND; they were $3.20/ea US, and sold individually. They're the semi-captive slotted ones like the one on the center binding post in this pic:Perhaps you could find those from one of the UK/European vendors.-Pat

D'oh!!Do Mouser or Digi-Key sell in the UK? Both have them listed for the $3.20 US price, sold individually, though that's of course over here in the Colonies.

content: I was going to suggest double banana plugs with binding posts - I have a couple of these I think I got cheap off ebay - but then I looked up the price!!!http://uk.farnell.com/pomona/5165-0-blk/connector/dp/2001652I've always found TTi helpful in the past so with luck they'll just send you a couple in the post, else the home made job seems best as others have suggested.
