Hello all,
My name is Neeraj, I am from Maharashtra, India. I am 38, but new to the world of DIY Audio and am not from a technical background (I was a commerce student) but I am very much interested in audio.
Some years back, when I came to know that the expensive audio equipments can be made at home, I started studying from the very very basics of electronics and started learning etiching pcb at home.
Till now I have eatched PCBs and assembled Amp Boards like couple of designs for TDA7294, Couple for designes for TDA2009, TDA2030. Some transistor amps based on the design of Sir Marshell Leach, Honey badger Amp, Apex A14 Amp. Also OM2.7, OM3 and ISOTOP from Russian website. Some preamps like P20, P30, P4 etc, some Subwoofer filters including sub filter from Mr. Mile, also eatched some soft start, Protection pcbs, power supply pcb, selector pcb etc etc... All are working.
Using some of the above PCBs, I assembled some Stereo Amps and some 2.1 amps using DIY pcbs and Old Dead AVReceiver cabinets (bought from scrap) . All are working without any major issue and with regular improvements.
There were some failed projects too. some noisey preamps were there, some amp designs were there like Jat501, Apex SR150, Apex SR100 etc etc etc.
I have Zero knowledge of PCB designing as of now, hence I need to rely on PCBs designed by the experts. But I will start learning it soon. My failure to success ratio is 1:1 as of now will try to improve it.
After 4 to 5 years, One thing I understood very well that "DIY IS NOT CHEAP". You will always end up spending more on DIY then on a professionally made commercially available similar powered AMP purchased. Also there are some issues like getting good quality (Original) componants at an appropriate price. I have seen vendors selling componants at 3 times 4 times the actual price. And the most important part is DIY have its limitations, It is not imposible to DIY Good Quality DAC, Preamp, Digital selector etc etc but the cost to do that all will be hudge. But, for me, I am not in a stage where I can turn back, hence I will continue doing it and will try focusing on Class AB Power Amps Only.
Since I have read about Apex A40 Amp a lot and every body was loving the quality of sound it produces, I also tried to assemble it. But kid of failed as for now and trying to find a solution on the forom.
