transistor voltage ratings are only maximum, they will work just fine on lower voltages.

they are not run in parallel, that's a stereo amp.
you need one NPN and one PNP for each channel.

oups okay ,yeah i think i know what you mean , need mores wires in this case lol , did you think i can use setup of any matched pairs like 2X 2sd2439 / 2sb1588 i know these are Overrated , 160V , if i run it to 60V insead of 160V, what is chance that is work anything ? a transistor of 160V rating can be run at half Supply ? did it work like that? , using an overrated transistor in a less power supply , it will reduce Heat ? , and risk to Blowing transistor? , or it will simply destroy the power suply by taking too much current ? , sorry i have somes noobs question that pass in my head . but plz dont forget that presently i study hard in experiencing anything that look legit , thanks a lot for your time

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

so this circuit have 2Xnpn in darlington configuration , and 2 pnp too , i will try to replace that only by 1 pair 1 1/2 X Rated, like tip35C and tip36C and bypas the ''darlington setup and see what it will happen , maybe the amp will be not loud as should maybe it will Explode , but this amp is not destined to be drived at max , and not destined to survive at base it should deliver the tip35/36C capabilities at minimum that is not so bad
Experiencing time , COTTON SMOOKE

i have already worked on blowed Su-g70 and su -g90 Amp with same defect ( overheated power module ) after Reflowed Hbrid ic ( to replace slided transistors ,, the amp was able to get audio but not loud as should ( Probably because one of 2 pair of transistor was blowed and amplifier lost his half punch ) ,

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

the original module was 130w, a tip3055 is only about 75w afaik.
even the 2n3055 in a metal can is only 115w

hahahaha what if ?? i want a transistor , ok wich package ? , i dont want it in a package , just the transistor pleaze XD ahah

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

this look pretty sweet , but absolutly not sure because i know nothing in audio : i juste fuin love this wathever it is

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

something is not right.

the transistors should all match,
you should not be seeing bipolar(regular) transistors and J-Fets.

maybe the readings are wrong or one of the parts is damaged.

yep affirmative pnp devices are exploded this amp is an heat victim , pnp devices sliding trip

if this guy was capable ! i will be capable too , it not need much more to get it work , in the worst case , un capaciteur dans loeuil un peu de fumée , une histoire a raconter ahahah desoler si mon anglais fais dur je m'force beaucoup!

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

So far I cannot tell if the output devices are just plain NPN/PNP or MOSFET, cannot find the spec of the module to verify, they do not look like MOSFET.
You also have some ICs in that module too.

yeah ! and these parts have nothing writted on it , its probably under the solder

npn pair is still intact


but pnp pair is destroyed , i was able to test only one ant its one that returned a JETTE FETTE

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

its probably because one of the PNP ( fake j-fet?) device that not completly blowed , other one is burned , , the 2 other one ( npn look just fine )

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

thanks a lot !! so now , just need to find somes candidats the PnP device returned P-jfet , with 64Volt look like legit info ,

the orange home made box is nothing more than a simple atmega168 electronic device tester found on ebay for 17$ i love it

'1' are NPN (Collectors of both Transistor '1' are connected to +VCC pin 4)
'4' are PNP (Collectors of both transistors are connected -VCC pin 5)
BTW, what is the model of this amplifier?

[Jeff Pepin]

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

according to diagram of SVI ,

pin3=ch1 out
Pin4 = +60V
Pin5 = -60V
pin6 =ch2 out

so on my ''mspaint artwork''
both yellow 1'S marks Are +60V
Both Red 4's marks Are -60V
Both Orange 3's marks Are channel 1 Output
And
Both Green 2's Marks Are Channel 2 Output

it leave 4 Connection that is for the signal
