<p>Congratulations!<br>
</p>
<p>Looks like you've got the issue "rectified" and "smoothed out" :)</p>
<p>Interesting that it was an electrolytic cap that was causing the
short. Sometimes that happens!</p>
<p>Peter mentioned that the bridge rectifiers failing often. It may
be one of those small 1 amp rectifiers running near maximum
rating. You may want to replace that with one with a higher
current rating.<br>
</p>
<p>Some years back, I was given a "non-working" Tektronix 475
oscilloscope for free. Replaced all of the tantalum bypass caps in
it with low ESR electros and it worked like new again!</p>

<div>One more time, this list is awesome, and i really appreciate
your help ! </div>
<div>I've fixed this pdd14 !</div>

<div>So you were right, it was not a transformer problem. I've re
checked all the measures, and then checked the bridge rectifier,
and discovered that There was a big shortcut between the two
rectified outputs.</div>

<div>Both electrolityc filtering capacitors were totally
inefficient. I décided to change their values from 1000uf to
4700uf, same voltage (i only have these ones here..).</div>
<div><br>
</div>
<div>It's working, i've learned new electronic skills.. Thanks to
you !</div>

<div>Have a good Summer </div>
