about power supplies

gudday mga maam/sir...matanong ko lang poh how to eliminate humming and hissing sound in the power supply in audio???
how can i modified a simple regulated 9v dc into a clear no noise output???
slamat poh...

@ts..damihan mo nalang ng filter caps tapos kung ano ang dapat iground ay iground mo..pwede din gamit ka ng regulator at apply ka ng pangboost ng current..dami yan sa net..try mo search ts..

slamat sir alvin sa info...

matanong ko lng sir/maam possible po b ang 750mA n transformer ay iboost ang amperage nya???gmit ang mga ibang components???

pde po bang gmitin sbay ang dalawang 750mA transformer to have a 1.5A???

slamat po talaga sa repz poh...

tama. proper grounding at good reservoir

kong focus kau sa pag amplify ng current based dun sa source nyu na 750mA ay medjo mahihirap ka nyan sis... applicable pa ung pag parallel ng secondary ng 2 trafo

center tapped poh b ibig sbihin nyo sah parallel maam/sir???

what is the different about center tapped and multi-tapped in terms of performance???

which one is applicable in audio device/systems???

salamat...

Basta parallel ang secondary ng dalawang transformer. In phase at sameturns ratio at mas maganda rin same brand at same size.

Yung center tapped depende sa termination meron bifilar wound at continous wound. Mas maganda magparallel ng bifilar wound. In multitap naman karaniwan yung continous wound lang. Mas maganda doing series or boost mo yung secondary voltage output ng dalawang transformer.
