hi teslar, if you have any information at this amp design just let me know... thanks
class g amp
eesbiboi, if im not mistaken i found this design at 320volt.com, im not sure, because the article is russian, if you are interested building this amp let me know... thanks

It's a turkish site that also several schematics like the Krell KSA Mk2 from this forum.
hi c3p0..from what place in angeles you are located?

sir junm, sa pandan ako near marisol, but im working in dubai now... thanks for the link, i want to try that amp, i have stocks of transistors here (cheap price electronics keni😀)
Mosfetli quality output amplifier circuit 3 times the output power and the drive times used irfp9240 irfp240 and two op amp circuit is used to drive the circuit in 4558 in times of peace movements do not need to set for
Supply voltage is + - 60 volts and + - 1130 rpm position volt output is also the Source schema and pcb files: 500W-mosfet-amplifier-circuit-irfp240-irfp9240-power-anfisi.rar
CAUTION Be careful when working with high voltage capacitor circuit to make sure the connection / - connect the opposite polarity high voltage circuits large explosions could be insured before you turn the power line, use protective glasses

coolet.. thanks for the info, is that schematic correctly drawn? theres a low value resistor 3.3 ohm 1watt connected from speaker output directly to signal ground ( at the left corner of the schematic) maybe it will blow when driven at high power...thanks
can you attach the pcb layout and parts? i can't open it over here. we'll confirm it from that pcb layout.

coolet, theres no wiring layout between the output module and drive board... thanks

yes no NFB going to the IC. Is there no Layout for the PSU? it seems other parts is in the PSU like the D2012.

coolet, theres no psu layout, from the output stage picture you can see an extra transistor bolted from the heatsink, maybe its the d2012.. hows the stability of this amp without feedback?, and no vbe bias circuit for bias adjustment and thermal compensensation. thanks

yes thats it. maybe the feedback resistor is missing in the schematic, there has to be NFB on this circuit somehow, thanks coolet
