# 100 Watt Power Supply For Power Amplifier

Proposed power supply for amplifier 100W v-mosfet [ 1 ] is what appears in the above form. It has separated supply for the various stages of supply, stage for power, stage for control, supply for preamplifier and for stage of protection. Whoever wants it can suppress departments or add a power supply for each channel, separating completely the channels between them. For whoever it does not use the circuit of preamplifier and protection can suppress proportional coil..
