How to make PCB by ironing method

For make PCB you need PCB layout. Download the PCB layout and print it by laser printer on photo paper. Then cut the PCB layout. Then press the PCB layout by iron on copper clad board. Press the iron 10-15 minutes. Then leave the PCB for cool down 10 minutes. When the PCB will cool, put the PCB in water and move the PCB layout to copper clad board. Then put the PCB in ferric chloride [FeCl3+H2O] for etching 10-15 minutes. when etching will end, clean the PCB by water. Then make hole on PCB. And then press the upper side print of PCB. Now your PCB is ready, mount components by instruction.

How to test this Driver


Series light test - After complete this board don't forget to series light test. When you will on this amplifier via series light, it glow for some time (1 - 2 sec). Then series light will turned off fully. If the series light will fully turned off, then check the voltages.


Power Supply - For get best performance, use 60-0-60V to 70-0-70V 20A Transformer. And for 1600 Watts Transistor rail, use 16 pairs of 2SC5200 & 2SA1943 Transistor.

Check Voltages -


Check Biasing of this amplifier. Connect the black probe of multimeter, on Ground and red probe on C4793 Collector. You get = 0.5 to 0.8V. Usually we get 0.5V to 0.7V. But here we get 0.8V, Because this driver was not connected to full Load. When it will connect to proper 1600 Watts of Load, it will show 0.5V to 0.7V. But if you not connect this driver, to a proper load and it show 0.8V then no problem, it will work. However, it will not go above 0.8V


Then check Speaker Output and Audio Input voltage. Here you get no voltages 0.00V. If you get same voltages, then connect preamplifier to input and connect speaker to output.
