Hello Bill, it’s just a fuse, but built into the 3 pin power socket. Yes agree on professionalism of the unit...Tom Konigs work is amazing, he builds everything from scratch except for tuning heads. On basses he builds all the pickups, electronics, mills the bridges etc. he also makes the knobs.


The box for the power supply was Designed by Tom in CAD, Cnc milled in his workshop , folded in his workshop, powdercoated in his workshop etc. All of the screws have captive nuts. It’s a work of art in itself. He bought a new folding machine just to get the accuracy right. Last year he redesigned and rebuilt his milling machine when he decided the accuracy wasn’t good enough to make world class bass bridges from billet brass.


It’s a level of attention to detail that few builders ever reach (Alembic of course is one of the others)

Looks VERY nicely done!


A few questions: Does he make a rack mount version? Does the power regulation let avoid using a power regulator (could I drop the Furman and lose some weight) ? and what would be the cost for something like this?


This unit regulates the DC power to the bass not the AC power. Your Furman provides regulation, surge and over/under voltage protection for the AC power so no one cannot be substituted for the other.

Most Furmans do not provide actual regulation, i.e. a variable input voltage results in a stable output voltage. They provide some protection, but most are just glorified power strips.

I use a Furman AR-15 II in my bass rack. When Brian mentions voltage regulator and weight I assume he is using one or a similar model. However as you say the normal Furman stuff is really nothing more than a power strip protect by a metal oxide varistor.
