Re: [CZsynth] CZ Voltage Selector to handle 220v and 110v

2015-08-31 by Jérôme

Hehe, don't worry, even though I don't know much in electronics I already managed to assemble a DIY synth on my own and I already fixed a few other synths too. I didn't bring my soldering kit but I don't think this will be very esoteric.

If the selector is not soldered and doesn't require to take everything apart just to access it I should manage to do it. In any case, if nothing bad happens, I'll let you know how it works!

Regarding anything to do with Mains Power: "I think I can work it out" is dangerous.

Get someone to look at it if you don't know what you're doing.
We want to see you around on the list next month!!!

Hi Daniel,

I think I got an hardcopy of the service manual so I'll take a look at it. I don't really know how to read schematics but I should be able to figure out.

I'll have time to look at it tomorrow and I'll let you know how it went. If I can find it I'll take pictures of where it's located to post it somewhere because I couldn't find much about this online...

Thanks & have a nice one,

Jérôme

According to freely downloadable Service Manual (not the best quality)
this instrument has universal transformer with voltage selector in
primary circuit. Voltage selector is in the list of parts, so it must
be somewhere. That means no soldering or reconnecting cables is
necessary.

Because such selector is not described in Owner's Manual, it's inside
the machine, somewhere in PSU circuit near the transformer.

During changing the voltage pull AC cord from the mains. Good luck.

Anyway I don't think you can destroy it even when connected - Canada
has 120 V, Europe 220 V. It will just not work.
