Hi,
A friend of mine blew his Chorus Ensemble CE-1

So, after checking everything the transformer shows no output voltage and I can't find any info on how much volts should it give to the PCB
Does someone knows if there's only one version of it?
greetings from Chile
Well...
According to the schematic I found here:
http://www.generalguitargadgets.com/boss/BossCE-1v2.gif
It looks like a step down transformer from 120VAC to a center-tapped secondary that provides 18V-0V-18VAC should do it. They are pretty common so I would think it is just a matter of finding one that fits the voltage, current, and size requirements you desire.
Good Luck ;D
P.S. Apparently, there are 2 versions of the pedal. Both schematics are on the GGG website!
The transformen has only two output cables ... They get to a dpdt power switch And then to the Pcb ... So i'm a little confused

As you can see in the schematic, the transformer SHOULD have 3 outputs. 2 of them do go to the DPDT switch (those are your 18VAC outputs)
The 3rd output is the GROUND that is used for the circuit. I do not know how yours is wired up but, the PROPER way would be to follow the schematic and use a center-tapped transformer. I believe the "proper" rating would be 120VAC input and 36VAC output CENTER TAPPED.
EDIT: Some older transformer-based pedals either clipped or did not use the center tap on the secondaires. Instead, they just tied ALL of the ground points together and I believe they went back to the neutral connection of the primary or the Earth connection of the power plug. I would advise going according to the schematic though :-X
