This is a scheme set 1000watt power amplifier. Currently I do not have a picture to the circuit board, but because the amplifier circuit is quite simple, you can design it yourself PCB easily.
the assemble cables for DC power supply and output transistors must be large, use size 1.5-3mm for large current passed. The Power supply of this circuit used transformer with 20A/45CT( transformer with center tap) and at least 4x10000μf/80 volt or 2x 22000uμF capasitor. this circuit is able to supply power 10000watt therefore the power transistor will be very hot, give good cooling fan on the power transisitor.
Transitor alternative to replacement of the 2SA1494 is 2SA1216 From SANKEN. The transistor has a 200-350 watt power dissipation of each pair so that for long-term operation of more durable. Keep in mind, usually sold a pair of power transistors with its complement, so you can not buy 2SC2922 alone without 2SA1216 or 2SA1494 without 2SC3858. The price range for transitor tsb is 30-40 thousand Rupiah's/ pair or US$ 3-4/pair
