Before I make an error, can someone kindly tell me the correct size of the TC-7520 DC input. Is it a 2.1mm barrel/tip or smaller?

I bought one of these http://www.maplin.co.uk/power-tip-connectors-44240 from Maplin yesterday for my Caiman and the specs show it as 3.5 x 1.5 mm
(code AQ91) - just measured the barrel to check and it's 3.5 mm external diameter.

Thanks. From their website - AQ91Y H 3.5 x 1.35mm power.

So it looks like 1.3mm is the tip's internal size.

I need a barrel adapter so I can press gang a spare 12v SMPS into use - 2.1 mm to 1.3 mm should do the trick.
