  • Simaudio 820S, Part 5

    My college years were pretty miserable, but unlike any other place or point in time in my life, being on campus meant there was a chance you'd see not just the guys, but the coeds take off their tops.

    Decidedly unsexy, but educationally necessary, let's take off the Simaudio 820S' top. As you can see, the 820S' innards consist of 5 neat sections.

    Starting from the rear are these circuit boards, attached to the DC power jacks.

    Up front are the caps and "shielded inductive filters."

    This could be the most important part of the 820S. Remove the center metal cover's four small hex-head screws. No, those toroidal transformers are not boobs.

    Removing that center metal cover reveals the circuit board, which holds the two fuses. WARNING: the manual erroneously specifies these as slow-blow, 20mm, 0.2A. Much more on that, in a future post.
