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.
Would swapping an EL34 to an original KT88 circuit with proper voltage adjustment gives a better in vocal part but still able to keep the bass responce?
Sorry maybe this question is a bit confusing but i am now very confusing about the tubes
