Voltage conversion of Accuphase E-650

Hello @imhififan , thanks for your support of audio hobbyist!

I used your instructions and switched the E-650 to 220-240 volts:

I moved the connectors to the third row (K7, K8), disconnected the jumpers J1 and J3, installed the jumper on J2. When the amplifier is turned on through an incandescent lamp, the amplifier indicators do not light up. It should be?

What’s the wattage of the incandescent lamp?

@imhififan Incandescent lamp power 100 watts

Two possibilities:

1. The incandescent light bulb too low in wattage

2. Short circuit

@zeptul

According to the specs E-650 draws 168 watts @ idle. Please try a 250 or 300 watts bulb. If that does not light up the amplifier, you need to check the soldering of all connectors.

I checked everything, the amplifier is working normally from 220V.  Thank you again!  Good luck! 

Sincerely, Victor
