Accuphase E-408 voltage conversion


Hello,

Maybe someone has experience in converting the voltage for the Accuphase E-408 amplifier from 100 volts to 230 volts?  I tried to find this information on the forum, but without success. 

I would be grateful for a photo of the board with the location of the jumpers for 230 volts.  

Sincerely, Victor.

I did everything according to your instructions. Jumpers J3, J4, J8 installed (240 volts). The rest of the jumpers have been removed. After setting the jumpers to 240 volts, the resistance between the contacts C2 increased from 0.5 to 2.1 Ohms. Connected power through a 100 watt light bulb. At first, the light bulb burns brightly, then gradually the glow decreases. At the same time, the VU meters light up. Didn’t notice a burning smell. I recorded a video, please watch. Is this a normal reaction? Is it possible to turn on the amplifier directly without a light bulb?

Looks perfect!

The bulb lit up in the first second is due to inrush current  as long as it dim down after that. It is perfectly OK! 

Please go ahead plug it in directly to the mains outlet.
