I’m in the (very slow) process of building a DIY amp. One of my goals is to keep the footprint of the amp as small as possible. Towards that, I’m considering building an external power supply (linear).
In various amp reviews, people seem to really dislike external supplies. Mostly it seems they dislike the aesthetics (which is cool, but it doesn’t bother me). I was wondering, though, what some technical issues might be that would make external an issue.
I’m using an ICL combined with a relay to limit inrush current, as well as a relay to only turn on the +-12v and 55v after the capacitor bank is charged. I’m also planning on two switches: one to disable the psu completely, and one that is effectively a standby switch ( turns off the voltage outputs, but not the AC)
What else should I be taking into consideration?
