Orange AD200B input jack socket temperamental

Hi, I have found that the passive input jack is not working as it should on my amp i.e when in use there will be no sound unless you wiggle the jack a little. The active one is fine. I have had a look inside and all the soldering is solid. Would it just need a clean or replacement? If it needs replacing is it a straightforward job? I would assume it can be any similar one from maplins or somewhere like that.
Thanks

Hi. If the solder joints are good then I'd suspect it's dirty contacts on the active socket. If I remember right the input circuit uses the switching on the jacks to select the appropriate input impedance. A blast of switch cleaner should put it right. Use servicol, get it from Maplins. Spray it down the Jack socket using the straw and push a Jack plug in and out several times.
Cheers Just
