Hi folks, my laptop works only whit the battery's energy. If un unplug battery, laptop doesn't work. So I would think the power circuit on the mono is broken, BUT it can charge the battery! So I can't understand what's wrong. The power supply is fine, and I have tried different power supplies...

This amplifier has a protective circuit function, but maybe it is too sensitive? The amplifier clicks one time as soon as it is on phono, then pretty much as soon as the needle is lifted or about to drop, the amplifier clicks again and turns off. It only shuts off like this on phono. First, I...
