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.
ECC85 - preamp ; EL95 - output with 5k to 4 ohms transformer. Output tube is pentode wired, ultralinear configuration. 250V PSU voltage. What will be the power output? I gues 2-2,5W.
