Hi/Ciao Checco. A Ruby amp,http://www.runoffgroove.com/ruby.html , with it's Fet high impedance input makes a good preamp, if you use it without the 1K gain trimmer/pot.
It becomes a 20x gain clean preamp. On its output, instead of a speaker you can hook a 1Kohm resistor and reduce the output capacitor from 220uF to 10uF.
You can get 9V from the +35V LM3886 supply with a 1K1W resistor, a 9V Zener and a 100uFx25V capacitor.
If you find it confusing, I can draw a schematic.
Ciao amico e buona fortuna.
