40V dual power supply

This 40V dual power supply circuit was designed in response to a request made by Michael from Philippines. His application is to power the 150 Watt amplifier circuit published here.  I think this power supply design is adequate for the purpose. The transformer T1 steps down the mains voltage, bridge D1 performs the rectification, C1 and C2 does the job of filtering. C3 and C4 are decoupling capacitors.

Notes :

  • The T1 must be a 230V primary, 30-0-30V secondary, 200VA transformer.
  • All capacitors must be rated at least 63V.
  • C3 and C4 are polyester capacitors.
  • If 8A bridge is not available, make one using diodes like P600A.
