Bass and Treble control?

No, but I use a small stand alone Schitt Loki that offers 4 bands of equalization. Its better than just bass and treble. I find too it adds a touch of more clarity to the music. Good luck, its a wonderful amp for the money.

Power consumption seems too high? 250 watts? Idle or when in use?

Hello. Its the maximum power consumption. The actual power is dependent to the volume and speaker you use. This device won't consume more power than other similar amplifiers.

Is it easy to find tubes for this in the future?

Yes, it is a tube available directly from Nobsound. They are quite special tubes, that sound very warm, rich.

Can it be used as a preamp via its 3.5mm output?

Hello. Sorry it cannot. Its SUB output is only for active subwoofer and its 3.5mm output is only for headphones.
