This track (Everything Must Go, by Steely Dan) is flat-out THE BEST sounding kick-drum I have ever heard on my system. I hate the intro (cacughanous combination of sax, drums, guitar), but at the :50 mark starts perhaps my current favorite SD song…
Problem: Severe burning of the PCB around regulator circuits on dual channel boards that can lead to permanent damage
Solution: Full restoration!
The regulator circuits need to be rebuilt and modified to prevent future burning. Without service, these amps can be become UNUSUABLE.
