[sdiy] Roland tr-909 jack type?

[Julian]

Someone would like me to have a go at some problematic jacks on their 909 -

Just in case they actually need replacing, im just wondering if theyre of the same type as used on the tb-303 / tr-606?  From the 
few grainy photos ive found on the web, they certainly dont look like the tr-808 type...

Indeed, they could be neither!

Could anyone advise?

Thanks, Julian
