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 PP el84 amp with Lundahl LL7903 at the front as splitter and followed by dact attenuator and fets (2SK30A). It works fine with step up of 1:4. Can I expect better sound with LL7903 in 1:2 ?
