- Use + /-70V 10A DC dual supply for powering the circuit.
- For L1 make 12turns of enameled copper wire on a 1cm him: plastic formers.
- use 8 x IRFP448 MOSFETs in the final stages
- Heat sink is Necessary for the MOSFETs. A 8x4x4 inch finned aluminum heat sink will do. There is no such thing as a heat sink That is too large.
Also to what the name suggests this stage converts the voltage developed in the VAS and provides all the amps required to drive at 8 or 4 ohms. 2-ohm loads are possible for several minutes at a time. In fact, I have tested more than 1600 1kW amplifier Watts RMS at 2 ohms. But that would not be recommended as a long-term exposure at all. If it is higher than the figures of the STI-amp. Power to the AV amplifier 800 The components of the power for this amplifier are as follows, and are favored A channel or a power module alone. 1 toroidal transformer with a rating of 1kVA. Primary windings are made to fit
