parallel niyo lang sa power supply ang capacitor.

booster amp using mj255 transistor

Post by eysi on Sun Oct 02, 2011 3:18 pm

to whom it may concern:

I just want to know the turns of the two power transformer used in the circuit because you know guys I had a project that hasn't finished and I am trying to finish it but I can't because I can't find transformer such those.
That's why I'd rather to make my own If someone can tell me How many turns are those.
Thank you and more power.

sensya sis wla akong 500 watts na formula, nakuha ko lang yan sa lumang libro ni marconi pagarigan, almost 20 years na yan sakin enidit o lang kasi sira na yung libro ko sa katagalan. meron pa ako isang furmula sa paggawa ng power x'former kasama rin yan sa libro kaya lang di ko pa nakita. post ko nalang susunod kung makita ko na.

pwede bang mag parallel ng 4 transistors,bali 8 lahat ang total sa dlwang junction,sa 100W audio booster?

if 150W audio booster ang balak kung gawin,dapat bang baguhin ang value ng dalwang rsistor?

sir naa paba nay schematic diagram?
ug naa paba kay lain dha nga dali ug sayun ra himuon?
naa nay booster nako diri gbaligya rani sa akua,gusto nako butangan ug tone cntrol...

lahi lagi ang partlist ani nga booster ky 300 ug 20 ohms 5W ug 4700uF ang cap. pero stereo..nya AC na murag 10A man cguro supply ani. butangan unta nako ug tone kay ang ngdrive ani kay amp sa PC TDA2822.
salamat daan sa makasuggest
