WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
I have a question. If I have 2 mono final amplifiers, can I use as a pre-amplifier a dac?
This way:
cd player/computer -> dac -> mono final amplifiers -> speakers
you have two channel comes out from dac; I suppose you have also the volume.
The nominal ouput voltage from dac is 2 volt, normally is enough to drive an amp.
