KT88 Single Ended Tube Amp

Alex has put together a single ended (SE) KT88 tube amp. His design was based around Mikael Abdellah's KT88 SE Tube Amplifier design from 2003. Alex has made some changes, such as the ability to switch the amplifier between triode and ultra-linear operation. A picture of his finished KT88 tube amp is shown below.

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.
