The diagram above shows how the DC +25 V and-25V DC can be obtained. Ready to provide power to two stereo amplifiers, one 80VA transformer with 240V input and 36V output, with the center tap is used. The output of the transformer secondary repaired using four 1N5401 diodes and filtered through four electrolytic capacitors. A fuse and a varistor connected to the main circuit protection against voltage spikes.
