I changed the bridge for another one and still open the fuse. See the photo, all caps wired correctly._MG_2623.jpg

Think I founded the problem, missed a connection between first and second caps, just connected the last four caps with inductor., it is not too clear but think you can notice in the photo._MG_2678.jpg

Now time to to disassemble the hole thing.

hello. how is it working?

JPDuarte · 26th October 2010, 01:26 PM

Hello AudioSan, before anything, thanks again to reply and try to solve this problem, but sad thing is that the problem still persist, when the bridges are connected the fuse open after more or less 1 min. Right now Am a little bit disappointed and down.

This shouldn't be too hard to sort out.

Transformer works without bridges connected. Check voltages at secondaries with full power.

Disconnect caps and connect bridges to transformer and try. Check voltages.

Next, connect one bank of caps at a time and try. Check voltages.

you may have a short somwhere. is your bleeder resistors okei? (if you us them)
can be a foulty bridge too. the one you disconected last time.

JPDuarte · 26th October 2010, 09:49 PM

Voltages at secondaries without bridge 42.1 and 27 ac volts at full power. Secondaries connected to bridges, no caps plug in 41 vdc and 26.8 vdc at full power.

If there are no connections made to the secondaries other than your meter it would seem that your transformer is bad. It happens sometimes.

If you have a light bulb tester, wire a lightbulb in series with you primaries and see how much current the transformer is pulling.

Hi Bill , what voltages I have to get with secondaries connected to meter only ?
