4240 line conversion

[Traverso]

Hello,

Can anyone tell me how to make the line conversion from 220V AC to 240 AC for a 4240 quadri receiver.
This info not available at the Service manual.

Besides the 4240 PIC I Include the AC wiring as is now.

Thanks a lot

220 to 240???

 

[Traverso]

Yes!
here in France the AC delivered at home has increased from 220 to 235 Volts
Furthermore, most of the Marantz offer to double the voltage from 110V to 220V and also include secondary additional windings making possible an input of up to 240V!

I have a 4240 (American) but you can't change the voltage on it, so I can't help you. Good luck.

If I recall correctly, either the 2270, 2245 or 2275 service manual has instructions on changing the voltage. Try downloading the manuals. Perhaps the procedure is the same as for the 4240.

Edit-->Found this in 2245 manual:

I had a look
Not exactly the same color code and the actual wiring corresponds to nothing when compared to the 2270 wiring

Still to investigate

OK solved, I found the 2275 SM page 37 to be very similar in wiring and color codes to the 4240 I have here
