Accuphase E-408 voltage conversion

For the soft start resistors, J3 provides highest resistance and should be good for 220V/240V mains, therefore no changes required.

Thanks for reply.

I'll write a report after the changes are made.

Kind regards.

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.

I checked everything, the amplifier works well.

Thanks for your professionalism. You have done me a great service.

Kind regards,
