gawa po kayo ng dalawang ganito.


from book of pagirigan
BOOSTER AMPLIFIER (STEREO) using MJ2955 Pushpullamplifiermj2955boost

Note:

The value of R1 and R2 470Ω vary from one input transformer to another. Common value of R1 is from 4.7Ω, 10Ω, 12Ω up to 15Ω. In case of distortion, try substituting the value of R1. In case of excessive heating of output transistor, try to substituting R2 470Ω with a lower value say 330Ω or 390Ω.

nandito po ang ibang information

wla nmang dapat i-eliminate dyan.lines crossing without a dot is not connected.mas maganda kong mas mataas ng driver amp.pwede an7161 or tda2005,khit yong mga car stereo na 35w.mas maganda ang bass kapag malkas ang drive,wag lng masyadong mataas.nasubokan kna sakura[nkalimotan ko yng model#,yong TIP lng ang output trans]ang ganda ng bass.lakihan lng ang input trans4mr.

ibaba ng kunti yong ground resistor.example:470ohms,gawin mong 400ohms.kung masyadong mainit yong pwer trans,itaas mo yong value.
