Can I get 400 watt mono, if I add two more pair of 2sa1943 and 2sc5200 in this same circuit and I will use 40 0 40 15A, Transformer ?... 2SA1943 2SC5200 200W Amplifier Circuit
Hy My name is Sagheer Ahmad From Pakistan.I like this Project. I need a High Voltage Power Supply. So Please share Resistor Value R23 or R27 Or Transformer Winding Data. i want to make this supply a turn any fixed voltage variable power supply.

Hy dear my name Is Sagheer Ahmad. I am from Pakistan.I like this Power Supply Project. you did not add the Top silkscreen of the power supply design to the Winrar file.Please i want to make this supply.... Adjustable power supply
Nevermind. Stupid question. I've already done this amp. Works "fine" with a series old filament bulb, but I have -0.4V (negative) on D2 cathode, when it should be 0.6V (positive), am I right? If I'm not wrong, one or more of Q4, Q7, Q9 (2SC5200 near to negative voltage) is(are) damaged. Every other measurings are looking fairly good, perhaps the VBias (0.8V) is a little bit high.... 8-OHM 100W RMS Amplifier 2SC5200
@J c:
I noticed that R1 is connected to the output of the regulator as is normal but in this case I would have thought that it should be connected to R13 at the output giving better performance/ stability as it controls the output, taking into consideration the voltage drop across the two emitter junctions and the variable load conditions ....

Looking at the pcb for this project, I believe you have the labels for T3 and T4 reversed. Also, I cannot see where the 12v supply links to T4c and R8.

@george:
I built this smps ,using every thing on the diagram and wound thetransformer accoirding to your specs. The 0.8mm wires are much too thick to wind all the turns onto the ETD29 bobbin. The core itself cannot handle 300watt according to the data sheet. The moment I switched it on the output rectifier combination burns out. I replaced them but then the MOSFETS burnt out. The pulses from the 2153 are correct but is it possible that it this IC can cause that problem ? Can a fake IC cause that ?... IR2153 Audio SMPS Circuits
