Here is the circuit of power supply, for Power amplifier 60W Class A. He is one relatively simple and classic power supply. In the line of input, exist, the classic circuit of protection and soft start. In the circuit appear two transformers. This can change and all the coils they become on one transformer. What it should we are careful, they are the cables that transport power voltage ± V1 [ ± 40V ], are also big cross-section with investment of silicone, so that, they bear in the currents that they will go through from in their, but also the temperatures in which they will be found. The connections in the various points should become with screws. For other two coils of transformer, does not need something particular. If you did not need the coil of ± 15V, we can suppress, also the supply of circuit of protection, it become from the other coil of transformer. Attention should be given in the region, round relay RL1, in primary of the transformer, which should also header well. The bridge of rectifier BR1, should bolt in some point of chassis, so that is frozen. Obvious is that will be supposed exist a transformer, for each power amplifier.
