Amplifier Design, Operation and Testing

Paano gumagana ang Amplifier at paano ito dapat itest kapag binili o gumawa?
Dagdag kaalaman po ulit sakaling hindi pa natin alam.
Lahat po ng computation sa video ay approximation lamang
at hindi pa kasama ug peak voltage at peak current computation.
AD MC4000 first gen (Class H) ; 1000W@8ohms x 2ch
Transformer: 96-0-96 ; 48-0-48
Reservoir Capacitor: 12000uF x 8
AD MC4000 first gen (Class TD) ; 1050W@8ohms x 2ch
Transformer: 49-0-49 ; 49-0-49
Reservoir Capacitor: 4700uF x 8
Formula used:
Power = Voltage X Current
Power = (Voltage X Voltage) divide Resistance
Voltage at Speaker = squareroot of (Power x Impedance)
Ie = Ib + Ic
Ic = Beta X Ib
Vce = Vcc-Vspeaker-Vre
Power Dissipation as heat = Vce X Ic

Hi sir. Thank you sa mga videos nyo very helpful. Tanong ko lang sir if meron kayo formula kung papano makuha RMS rating ng amp through its component nya? And pati speaker sir meron dn ba sila computation sa peak nila vs rms?

Hi Sir David, Ang lakas ng ampli sir ay nasa PSu, Ang amplifier Sir ay may tatlong klase ng PSU. may bukod po ako na video doon kakapost ko lang din. :)
Let say unregulated po ang gagamitin natin, pinakamatibay na PSU pero nabagsak ang voltage kapag may speaker na na nakaload.
halimbawa po ung PSU, pwede sya pumalo ng 110V kapag walang speaker, kapag niloadan po ng speaker magiging 100V na lang.
un pong tanong ninyo na RMS ng Ampli ay pwede makuha by using voltage saka current rating ng PSU.
Ung speaker naman po, wag ninyo gagamitin ung PEak rating nya, laging sa nominal rating kayo mag cocompute. Ung peak rating po ay nagdedefine lang kung gaano kataas ng headroom bago masira ang speaker. :)

Additional sir, need po ninyo iless ung Vcc or Vdd requirements ni Transistor, then ung minimal voltage drop kay Re (negligible)

slmt sir at nalinwan ako, kc myron ako clss td mc4000 bkit kaunti lang trnsistor nya pero pag ginamit ko hnd nainit kht dlwng speaker sa isang chnnel gngmit ko

Thank you bro. 💕

ang class td ay kahawig lang ng class d,kaya hindi talaga sya mainit
