Help with repair of valve amp

[Wiggins]

Hi Everyone
Just heard a loud bang and coming from amplifier. Now there is no sound on the left channel. It is a Cary SLi80 valve amp.  All the valves are still on.  Anyone in Cape Town (Somerset West) that can help with repair?
Any recommendations are appreciated
