Northstar DAC

                       

   

 

   

 

A customer brought in a Northstar Upsampling DAC with excessive hum, and static noise.    Bench test reveals that the unit was leaking DC voltage due to transistor failures.

 

We took the time to find 2 matched transistor out of a batch of 400 !   We test each transistor individually find two with matching characteristics.   The process was extremely time consuming.
