Help with Sansui AU3900 - Pops and cracks but nothing else

[TGJ001]

Hi All,

 

I've just pulled a few bits and pieces out of storage for a play, one of which was an old Sansui AU3900 which is still in lovely cosmetic condition. I plugged her in last night and it powers up (I can hear the usual relay clicks etc) but all I can get out of it are pops and cracks.

 

The cracks are very loud and don't seem to be influenced at all by the volume control. I popped the lid for a quick inspection but everything looks OK visually as well as minimal dust etc. I can only spot one main fuse at the rear which is obviously intact as she powers on. I'm thinking it's probably dead and beyond my skill level to repair but I'm reluctant to give up so easily.

 

Any ideas?

 

Cheers,
Tim

It will be faulty transistors in the tone amp stage.
