Quad 44 Pre amp, in need of urgent help and attention

Greetings, i am in need of some help, i have a small problem with my Quad 44 pre amp. When i select my auxilary input, it does not seem to work on the left speaker, when set on stereo, but works fine on both sides if on mono. I opened up the pre amp and found that the rca connector for one channel to the circuit board snapped, just at the tip of the connector. I tried soldering it back together, but instead now there is a crackling sound or no sound coming out from the left. I was wondering if anybody knows somebody who is able to service quad amps in KL or even Malaysia. Please do help. Thank u.

someone give this guy the contact of that hifi repair dude at Old Klang Road .....

Thank you guys very much... u guys are awesome!
