10A 70V SMPS for Power Amplifier

Before the making of Gacun SMPS circuit for a power amplifier, we must know in advance what it is Gacun. If you are an electronics hobbyist who often dabbled with Power Supply TV, then you will not be familiar with Gacun module.

Kit / Module Power Supply Gacun is a very innovative breakthrough. Can be applied to any regulator including TV, as long as the transformer is still good. With this kit, the technicians are very helpful to replace the original regulator circuit.

In this article, we do not discuss more deeply about how to apply/install Gacun for TV regulator, but we will make power supply amplifier by using Gacun module which I will share what kind of Gacun circuit module itself. Which I have previously published on how to create an SMPS circuit with a poison module in this article: Switching Mode Power Supply 10A 20-50V DC CT

The following is an SMPS circuit 10A using Gacun more detail:
