Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

The transistors base drive circuits may be damaged when the power transistors went out, they are direct couple circuits. You should plug the unit into the AC socket that will put the 120V lamp in series with the unit you are working on. you can use 60~75W lamp, the lamp will stay on bright if the circuit draws too much current constantly, it saves me many output transistors.

Then the fuse blowed ,
i will remove the 4 transistors then try again without load ,

theses pnp/npn come from a non working amplifier , so i asssume they leak level 100

no smoke it will work , , i'm persistent

wear eye protection - resin from power transistors travels a long way

i wait this moment since 2 days now , then now i fear to plug it . ajaha okay i test that , it work or it blow , what can i do for check before putting AC on it? any hints ? ohh noo no question to plug this amp without recording that ! , phone need to be charg'D

That is such a great web site that have so much information. If you have to read them you will learn so much.

fOR SURE I WILL

Done !

"For the pnp transistor connection is
Collector = Power Rail negative
Base =Stage output (audio out)
Emitter = Signal input (audio signal) "

Emitter is the output. Emitter of the NPN and the Emitter of the PNP are electrically connected together to form output pin for driving the speaker.
See figure 4 for basic push-pull output.

yeah thanks i have just take conscioence of that , PNP^push on speaker , NPN pull on it , at itle Both center the speaker to 0 in function of the bias setup , i think i know a new book now and i fkin love that

dont forget to insulate the transistors from the heatsink so you dont short all the tabs together.

they are allready , they are plastic encapsulation h-30min before my capacitor in an eye

final schematic , comments? anywone see a FATAL ERROR ? otherwise its time to assembly the whole thing and put 115Von it

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

BTW, as far as the Wattage rating, the Transistor will dissipate the most power when the load is at half power.

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

he said, 120 or higher.
so at 160 your fine.

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

Transistor should be rated at x 2 of what the Voltage it will be exposed to. So you should get the transistor that is rated at >120V.

what is your reccomnedation for a +/-60V rail ?

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

just to be clear ?
for the npn transistor
Collector = power rail positive
Base = Signal input ( audio signal)
Emitter = Stage output ( audio out)

For the pnp transistor connection is
Collector = Power Rail negative
Base =Stage output (audio out)
Emitter = Signal input (audio signal)

nothing wrong ?
