  1. There's more info here on how to build the thing:

    In case some of you are wondering, a stepped attenuator is a top notch volume control unit. In a normal potentiometer, the audio signal passes through the thin carbon track, even in some high end pots like ALPS blue velvet, so this may degrade the audio performance. In the stepped attenuator, the audio signal only goes through 1 resistor, thus maintaining as much sound quality as possible.


  2. Goot agent is in basement of Sim Lim Tower. Very nice couple owns the shop. I recommend a temperature controlled iron, no need for station. Save the money for your other purchases. I use a 70W temperature control iron and it's fine, even if I forgot to turn off at night and left on for 24 hours.

     

    Hmm.. how much does that cost? Does it have variable temperature function like a soldering station does? ESD safe?
