Jean Hiraga's single-ended KT88 tube amplifier schematic with 12AX7 (ECC83) tube input stage. With a number of different KT88 tube amplifiers we have had good results using new production JJ KT88 Blue Glass and Genalex - Gold Lion KT88 tubes. The power supply uses a 5U4G tube rectifier and a C-L-C filter. More information about power supply design with tube rectifiers is available in the Power Supply Design for Vacuum Tube Amplifiers article.
