Power Supply
This Power amplifier uses one 3 KVA toroidal transformer. A soft start is provided using relays and resistors
(placed on the switch-ON board). The high voltage is made by combining 4 x 575V AC (total 3200V DC @
1,2A . Each has its own rectifier and filter. In the high voltage circuit, safety resistors and fuse are employed
to protect the amplifier against overload (placed on the power supply board).
