INi postingan yang desain APEX..MR.Mile Slavkovic di www.diyaudio.com:
1. "I used TL072 on some PCB, at the end this is PA amplifier, work with 18inch subwoofer".
2. Full power of this amplifier is not 900W. Power with THD 0,5% is 1200W on 4R load, and 1800W on 2R load. Output transistor must be MJL4281A/MJL4302A for maximum power. For step mosfet use IRF2807. MJL21193/MJL21194 can be used for full power on 4R load.
Transformer minimum 1500VA for one channel 4X40V AC + 2X20V for protection circuit. 2X35A bridge and 8X10000uF/63V for PSU... are you still interesting to build this amplifier?
Silakan rakit dengan komponen, TR final dan PSU yang disarankan oleh perancangnya...pasti maknyuss utk 18"
