• I have a problem with an amplifier - no sound output on left channel. It is intermittent, but I don't know whats causing it...

    Happens on both line and phono inputs, and on both speakers A and B. tried with 2 different turntables, line inputs, etc.

    The fact that it is intermittent, (although only occasionally work) gives me some hope it's not serious, but I'm fairly certain it's something internal.

    Who in London would be recommended to have a look/fix? Pref North/East or Central.
