Lots of capacitors in a CLCLC configuration + a shunt voltage regulator: a high-end power supply for preamplifiers, phono stages and other HiFi equipment. The shunt regulator can run with a quiescent current of up to 500mA. With the onboard heat sinks, that you can see on the picture, the regulator ran well with 250mA quiescent current and no external load. In this configuration, the power consumption of the circuits is the highest, because the regulator has to “burn” the full quiescent current.
Both PCBs are available in our shop: UniSieb, Shunt regulator or as set of both PCBs.
The new PCBs for the shunt voltage regulator arrived. Now final testing starts. Unfortunately I ran out of electrolytic capacitors of the right size, therefore it will take some more days until the tests can go on.
One cool thing of about this new PCB – by just changing two jumpers you can select between 3 different quiescent currents. This makes it easy to adopt the circuit for different use cases.
The VSPS was a project built years ago. It was based on a design of RJM audio. The biggest issue of the VSPS is it’s limitation to MM system. But if you use an MM system, the VSPS is worth a test. It is a very inexpensive phono stage.
As the name suggest, SimplePower is a simple power supply for audio devices. It uses a pair of LM317/LM337 to provide a stable output voltage. Add a transformer and you get a symmetrical power supply. This power supply will be used for our QuadVol project.
I’m working on a new version of the K+T shunt regulator. The old PCB was very similar to the original K+T design. The new version will be bigger, but completely integrated for a symmetrical power supply.
The universal rectification and smoothing PCB is now available on circuits.io. You can order PCBs there or fork the design and use it in your own designs.
The Shunt regulator PCB from Klang + Ton is now available on circuits.io. You can order PCBs there or fork the design and use it in your own designs.
