So my late model serviced Olive 52 developed an intermittent left channel fade-in/out and complete dropout issue about 4 weeks ago. After running my own diagnostic checks, ie switching the 135s over to rule out power amp failure, and then switching all interconnect/ Sniac cables, Burndy check, the left channel dropouts still persisted which was worrying to say the least.
The only thing that temporarily brought the left channel back in operation was to repeatedly press the mute button, but after a short while the dropout issue would return.
To cut a long story short, the unit was sent to Salisbury after speaking to tech support. They suspected the output relays were probably at fault.
Anyway after a super fast turnaround (10 days) the unit was repaired with new relays, ready for collection at my local Naim dealer.
One week into the warm up the 52 is sounding even better than before, improving in SQ every day.
Big thank you to Graham who carried out the repair ![]()
