Hey destroyer X! i've rebuilt my first transformer!

benmanf · 8th August 2004, 08:11 PM

yay!
thank you destroyer for your help (how to rebuild a transformer)...
remember me?

well...
my first powerful, exellent working transformer is ready!
it took me alot of time to find an old transformer but it took me only 2 days to rebuild it!

well now it gives me exactly 25.3V each side (25-0-25)
and with some of the remaining wire i maked 12V for
accsesories in my amp, not making any bzzzz noises...

i tried to connect a diode bridge and the two 4,700mF caps,
well...it gives me 35.1V - exactly what i need...(35V)

i need only a 100mF 35V cap to complete my amp
(i bought 16V instead of 35v

)

tnx destroyer!

OOPS HERE IS THE PIC

If your output is 35V DC, your going to want to buy 50V+ capacitors.

Nice transformer though.

It is so good this feeling, i thank you because you trust me.

Now you are free!...you will do what you want!.... you killed the mistery, no more problems to you related transformers.

Very pretty benfmann.... mine normally worst than yours...you worked very well.

You saved my day, today here, father's day... but my girls were out the biggest part of the day.... i saw the ladies only at night... i felt loneliness.... and you put me up.

Thank you Ben.....hohoho.... saved my day!

thomas:
those capicators are not for the supply...they are going to the amplifier

...there is no need there for 50V caps
but thats not a problem to buy 50V caps

destroyerX:
No problem!

It is normal to use higher voltage units in the supply, and also in the amplifier.
People use to do that.
I never did that....had problems once or twice, because made invertion in electrolitic condensers polarity... and...boooooom!... a lot of dirty when they explode, also smells a lot.
The man is rigth.... and you not too wrong, it's OK! too.
