Anyone who has worked with a Luxman MQ-3600 knows how rare it is to find a unit with the original S-2084 power transformer still in perfect condition. Over the years, even without actual electrical failure, the transformer may begin to vibrate annoyingly, making listening unpleasant and signalling internal mechanical deterioration.
This is the case of a unit that returned to my workshop two years after its reconstruction. Although electrically functional, the transformer produced a disturbing acoustic vibration, caused by a loosened bobbin, likely made of cardboard, and by play developed between the laminations. In situations like this, re-impregnation can only provide a temporary fix: after a few weeks or months, the problem reappears.
The definitive solution: SB-LAB 23S45
To avoid short-lived and unsatisfactory interventions, I designed a new power transformer intended as a compatible and functionally equivalent replacement for the original Luxman S-2084. The result is the SB-LAB 23S45 model, now also available as a standalone spare part for technicians, restorers, or enthusiasts who want to restore their MQ-3600 to full working order.
