    Well i read some stuff on the net bout the rectifiers and all that but its way to complicated. I feel really ashamed to say that i am an Electronics student :(. Gosh i shud hav studied all that during my BE.
    I really wish someone is there to explain all these to me practically. I would so love to build small stuff myself..

    i've been using the power supply listed on be3amplifiers site for 4-5 months now. works like a charm and i'd highly recommend it to others. as far as i know, ansar makes them himself and if i remember correctly, it can power upto 15 pedals.. tho i use it only for 3 pedals.. :)

    at 1800 bucks, i think that's the cost of approx 3 adaptors.. and definitely worth it..

    well, if he makes them himself then that's even better, I would say.

    @mymusicmyguitar: shame shame puppy shame! :D this is *very* basic electronics... i taught myself this stuff practically off the net before starting engineering and ansar isn't even an engineer, he's a compsci major... definitely try to solve basic problems like these, because it's a BIG help. you don't have to rely on the self-proclaimed "luthiers" or "techs" at music stores with 2-3 weeks of waiting on your repair. i've seen stuff repaired by "specialists" that just appalled me. so pick up some basic skillsand revisit that knowledge. it'll help you take care of smaller problems if you have any.

    He manufactures it himself... So that makes it even more reliable ..

    wht d hell man ! i made my 1st DC adapter when i was in std 10th...just becuz i knew abt a bridge rectifier and capacitor....in 12th i read their theories and made another variable AC to DC supply (220V~ changes to 1.5V to 12V DC) followed by a 5V consistent DC supply adapter.....and both of them still work smoothly (after 2 years)...

    if u wish i can give u circuit diagrams too....if u r good in the art of soldering...its freaking easy man ! leave diode and capacitor's theory, just follow the diagram and u r the master!

    If u want to power more devices u have to use a higher value transformer (more ampere=more power)

    and m a network engineer by diploma and NOT a B.tech holder :)

    This thread sounds (or reads/looks) mighty interesting. Had a small doubt..

    As I understand it, the noise in a daisy chain is due to:

    1. 60 cycle hum / ripple in the dc after ac to dc conversion
    2. Ground loops due to common grounding of all the pedals

    For the first problem, we can make a filter circuit to reduce the ripple. Now what about the second? How do I get by the ground loop problem?

    For me, when I power one of the pedals through a second (identical) adaptor, the noise reduces drastically. So would it be safe to assume that the noise in my case is mostly due to ground loops?

    PS:The last time I had anything to do with electronics was atleast 5 years ago. Please excuse the noob-ish-ness / dumb questions.

    Well to be frank its interesting but its time consumin too. And i dont think so i hav that urge to do it myself though i wud like to understand whats happening inside.

    Yup do send in those Circuit diagrams. I will go thru those and try to understand. Well yeah its been almost 6+ years now after engineering.
