In January 2020 after a decade of supplying audio upgrade DC power supplies for countless audio and video related equipment, we introduced our first BOTW AC audio upgrade power supply. The BOTW AC is designed as an upgrade for AC powered audio devices such as phono stages like the Benz Micro PP1 and as a 1 on 1 replacement for stock supplied basic AC/AC power supplies, which are supplied with turntables from brands like Rega and Thorens.

The design is based on our successful BOTW P&P ECO MKII model with all the necessary features to make the difference.

Why the BOTW AC?

A stock supplied AC/AC power supply in general is nothing more than a low cost “EL-type transformer” in a casing. The BOTW AC power supply is an upgrade AC-power supply and is designed to ensure the most stable and low noise AC current that is possible with an AC power supply.

Stability

A low cost EL transformer has not only the lowest efficiency of all available transformer types, a major drawback is the very poor load regulation of this transformer type. The load regulation is the ratio of the AC output voltage measured with no-load and full-load conditions. With the low cost EL transformer this load regulation is around 20% or worse. The poor load regulation leads to instability and degrades the performance of an audio device significantly.

With the BOTW AC our goal is to ensure the highest load regulation as possible. For this we use a highly oversized audio grade toroidal transformer. The combination of the technical design and large power reserve of this transformer ensures a very tight load-regulation with ditto stability.
