Re: BOOSTER AMPLIFIER (MONO) using MJ2955
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.

Re: BOOSTER AMPLIFIER (MONO) using MJ2955
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?

Re: BOOSTER AMPLIFIER (MONO) using MJ2955
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

Re: BOOSTER AMPLIFIER (MONO) using MJ2955
ok ra na kc ang booster puwede ka mag mods pwede sad templahan (as we call it here) ang 2822 ky hinay ra kaayu ug output mao nga dili kusog iimo booster ,naa schematic somewher in this forum .

Re: BOOSTER AMPLIFIER (MONO) using MJ2955
Sir Ultrasonic newbies po ako. nakabili po ako ng 30W bass guitar Amplifier Roland cube-30. Pwede ko po bang ikabit itong booster na ito para maging 100W output? hindi kaya ma apektuhan ang original output frequencies? or kung may kilangan pa akong additional components, ano po kaya ang dapat. Salamat po.

@ Ultrasonic .. ano po ba kaibahan sa
200 watts output trans4mer w/ secondary
200 watts output trans4mer w/out seondary?
thx

Re: BOOSTER AMPLIFIER (MONO) using MJ2955
gaano ba kalaki yung baterry ng motor mo? baka d kaya ng battery mo kaya humihina agad yung sound...may u box ba motor mo? try mo bnk bk-700...tama lang sa batery ng motor...usb player,auxillary in,may fm,stereo na cya...75watts per channel,may remote control pa,ganda sound nya...

naa ko nakitan uban 4 power trans...pwd??
ultrasonic™ wrote:no need to xplane na yata eto , kahit sino familiar dito most common amplifier circuit kahit sino marunong gumawa nito. magtanong tanong nalang kau or just ask nlng sa forum nato
add trivia nlng BOOSTER amplifier in electronic term are known as a PUSH PULL TYPE amplifier
gitawag na xag push pull its b-coz its hav two power switching transistor na magpuli-puli ug on ug off ... pangutana nganu kinahanglan mn mapalong palong ang operation nga pwde mn naka-on nlng pirme diba? ang tubag ana kay of course kung dli magpalong palong ang operation understood or sabotable na DC out ang labas sa audio output nga dili pwde sa SPEAKER kay masunog xa.. dapat AC signal lng ang iyang ginareceive.. (^_^)
now im xur naa na pud moy pangutana regarding sa power wattage ani.. pila kahay wattage ani? 50W kaha., 100W or mas taas pa?
ang tubag ana kay nagadefende na xa sa inyong power output transformer, kung 50W.. 50W pud ang labas ana.. kung gus2 nimu 100W of course 100W pud ang emng output transformer na gamiton.. but olwayz remember dis kung taas gani ang power output transformer nimu.. u must to add power transistor na MJ2955.. magparallel connection ka.. meaning ang base ikabit sa base, ang emitter ikabit sa emitter, ug ang collector ikabit sa collector ... e.g: kung 100W dapat duha duha ka transistor bawat junction, kung gusto pa jud nimu patas-an dungag na pud kag transistor gets ninyu? kung wala gani just txt me or ask lng mu dre ok (-_-)
SCHEMATIC DIAGRAM
COMPONENT PARTLIST:
2pcs. MJ2955 POWER TRANSISTOR
1pc. 470 ohm 5Watts
1pc. 20 ohm 5Watts
1pc. Audio input transformer 15Watts
1pc. Audio output transformer 50Watts (100W for 100watts operation & add two power transistor)
Aluminum Case & other accesories
PICTORIAL DIAGRAM / WIRING DIAGRAM
FINAL OUTPUT
naa ko nakitan uban 4 power trans.pwd ka mkahimo 4 power transistor og pra sa newbies sama nako pwd ba wla preamp diritso ra sa player..ang supply nga 12v o 24v pwd apil nimo post sa wiring assembly nga pic..advance thnz more power..

Re: BOOSTER AMPLIFIER (MONO) using MJ2955
hindi output trans4mer lng ang ngpa2lakas ng boster,kombinasyon yan ng lahat na psa.input,output,power transistor at suply.hindi mamodify ng output trans4mr ang rated power ng transistor
.ibig sabihin ba,pagnaglagay ka ng 20w transistor,tapos 500w ang output,maging 500w ang boster nyo?MALI!!!khit 200w ang transistor,at 12v ang supply mo,d rin aabot sa peak power ang transistor mo.kya aksaya lng sa pera ang malaking output.

Re: BOOSTER AMPLIFIER (MONO) using MJ2955
mas maganda kong alamin nyo muna kong ano ang rated power at maximum voltage ng tranisitor mj2955,pra magkaideya kyo kong gaano kalaking output ang gmitin nyo.TANDAAN!!hindi output trans4mer ang nagbi2gay ng power!khit wlang output trans4mer,kya pa rin itong mkaproduce ng malakas n sound,bastat may power transistor..TANONG LaNG:hindi nyo pa ba alam yong output tans4merless na boster?
