Simple Linear Bipolar Power Supply

This power supply is designed for stereo power amplifiers that require a dual rail power supply up to +/- 35VDC (with the supplied capacitors). If you are looking for an excellent linear PSU that comes as full kit, is easy to build, and has the versatility to work with your first build or your hundredth, this could be the one for you. If you are uncertain if it is the choice for your particular project, seek assistance.

It is verified to work very well with all First Watt designs sold through diyAudiostore.com along with popular Classic Aleph designs. 

This power supply requires a transformer with two secondary windings providing identical AC voltage, A.K.A a dual secondary transformer (not included). Popular options have been referenced in the build guide, but if you are unsure what transformers may be appropriate for your project, seek assistance.

FEATURES

• Dual rail decoupled - May improve channel separation and imaging with some amplifiers
• Simple to build with all critical parts included and a full build guide. Excellent choice as a first linear PSU
• Ideal for First Watt style amplifiers
• Low ripple and 176,000uF of capacitance
• Versatile
  • Replace the pi resistors with inductors (not included) for CLC filtering.
  • Terminal blocks are provided for AC and DC connections. Board are designed to also accept standard spade connections or be directly soldered.
  • Works wonderfully with Class A and A/B amplifiers
• A ground lift and soft-start are incorporated to the main PCB for ease of wiring
  
• Excellent layout to maintain short wiring for lower noise
  

Construction of this project requires working with potentially deadly mains voltage. If you do not possess the skills or knowledge necessary to safely complete this project, seek assistance and work under the supervision of a qualified electrician / technician.
