After repairs are completed, restore power gradually using a variac, to avoid overcurrent. Current consumption at AC 220-240V, 50 Hz in NO SIGNAL mode (volume min at CD mode) should be ~ 350mA. - Page 7 SA-AK350E / SA-AK350EB / SA-AK350EG 3. Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder remover device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate electrical charge to damage ES devices.
