The transformer should be a 230v to 6v transformer. No trouble for center tapping. No necessary for LPF as this is a linear power furnish. The diode employed is 1N5408, 3A, 1000v. C1 and C3 are 1000uF 50v capacitors, although you can use 16v caps. C2 and C4 are 0.1uF 50v ceramic caps. The IC is a immutable adversarial voltage regulator: 7905 and should be mounted on OK heatsink. You use a low-out of date cloth previous to to the transformer in ask for to sift out procession transients such as may be caused by dry-as-dust motors on the same mains in the running for switching on and off, or lightning. Without such filtering, the transformer and resultant parts may be subjected to voltages that may damage them. A "pi colander" is one way to change or best such transients. A team of paragon rectifiers such as a 1N4001 could be adapted to, but one must keep the on to the table voltage in deem insane. At 1A, a 1N4001 will have a Vf of 1.1V. If one hand-me-down a Schottky diode such as a 1N5817 will have a Vf of 0.45v at the same prevalent. You should probe...
