SSR04 Sjöström Super Regulator Power Supply Built
Ultra high performance dual voltage power supply with super regulator topology and an onboard transformer. It's a built unit. Delivery time 2-5 weeks. The regulator is hand soldered by Per-Anders Sjöström, the shop owner.
- Extremely low noise.
- Very low output impedance in the audioband.
- Well-known and well-tested in serious applications.
- Option for using two different kinds of smoothing caps, snap-in high performance or radial.
- LM431 reference but I have made markings for anode, cathode and reference so it will be easy to mount any other 2- or 3 pin device like LM329.
- Trimpot for both reference and feedback in order to trim the output voltage easily.
- Short circuit protection if wanted. When it's omitted you can have a lower output impedance.
- All resistors 10 mm so it is possible to use a cut and bending machine for those parts.
- Nice looking pcb with double ground planes, gold plated pads.
