Can recommend good hi-fi repair shop or specialist in KL?

I am looking for a good hi-fi repair person or shop to help me repair my Arcam Delta D290 integrated amp. 

The input selector switch has oxidised and gives a crackling sound. I checked on the web and apparently this is a common problem with this generation of Arcams. 

A quick fix would be to disable the input selector switch and re-wire the connections to use the "record" switch instead. Not sure if anyone can help?

Thanks.

Thanks very much. I will try to contact them.
