Re: 40W Power Amplifier
Hi Alvin,
I will post the picture of the coil maybe tomorrow
in that picture makikita mo kung ilan ang mga measurements
I was using a digital caliper that time but any ruler will do
I will check if I have a circuit for 2 channel mixer, parang may na post na si master ultra dito nun
The trimmer is for bias adjustment (Idling current)

Re: 40W Power Amplifier
Salamat po sir Danny...ask lang sir danny doon sa parts placement ng 40watts ay yung 1ohms ay nakapalupot po yung coil nya,ok lang ba yun?, yung resistor na paunta sa output ang ibig kung sabihin sir..^_^

Re: 40W Power Amplifier
nko sis danny.. si sis djfel ata ang nagpost nun... hnahanap ko din ang thread nya.. pero di ko pa nhahagilap ^_^
xa nga pala sis vin abwt dun sa L1.. di ko binilang ang turns nun sa akin... nagpulopot lng ako ng magnetic wire. cguro #30AWG un.. inubos ko sa body ng resist.. so far... ok nmn ang performance nya,,, di nmn umusok at still running pa rin nmn ^_^
sa trimmer.. 5k nga ang gnamit ko.. un lng ang pnakamalapit na availbale sa market eh.. ang alam ko ang purpose nung L1 ay pang isolate sa amp to capacitance load para maging stable xa...

Re: 40W Power Amplifier
kng tama ang memorya ko. .sabi ni SIr tony. tatlo daw ang Stages nito..
input LTP(differential or long-tail pair)
VAS, or voltage amplification stage at
output stage..
hhmmppffff mapag aralan nga to ^_^
