Hi there. I'm new to tube amps and I'm using a pre-owned Einstein 100W. It was really great and quiet, until last night. It became more noisy and the overdrive sounds weird. I also noticed that the blue LED named "inner" on the rear panel is on, right next to the text of "replace tubes and fuses".

Does this mean I have to change the "inner" tubes and "fuses"? And if so, which tubes are the inner ones?

Thank you for the help.

Not to be weird, but hi Mr. Diezel, I admire your work coming from a lowely EE.
