some times ago i bought a Little Dot LD Q+ Tube Hybrid Headphone amplifier.
Works well, looks awsome good... for me
From the beginning it had a small failure.
There are 2 LEDs.
A white one on the bottom side of the PCB. That's ok.
And a blue one on the top side, under the tube socket.
The last one did not work properly.
When i switch on the power, it flashes one time and then wents off.
I suppose it should light all the time.
Did someone know how to repair this?
Talk all about Little Dot products!
