Alex has done some experimentation with different tubes. EL34 tubes can be used in place of the KT88 valves. The preamplifier tube is a 6N1P, but the 6DJ8 / ECC88 / E88CC family of tubes can be used instead. The power supply uses a 5U4-GB dual rectifier tube.
For additional information, pictures and schematics, see the complete page of Alex's DIY KT88 Single Ended (SE) Tube Amplifier project.
