yun na nga gagawin q... last question po.. yung output po na transformer, ang bibilin q po ba yung may primary and secondary or pwede yung primary lang? kasi sabi ng nagbebenta pwede daw yung primary lang eh.... ask q lang po sa inyo wat ang babagay dun sa project q...

ang input, may primary at may secondary. wherease ang secondary, walang secondary.

imagine what is written on the schematic, yun na yun!

@ yhandz

Bakit naman may secondary yung bibilhin mo?..ang output transformer ng booster amplifier ay walang secondary..

try to analyze this circuit

yund transformer na malapit sa speaker yun ang output transformer
