KT88 Push-Pull Tube Amplifier (monoblock)

The third of the "OddWatt" tube amp projects. This one is the Odd Blocks which will work with a number of octal tubes (KT77, 6CA7, EL34, 6L6GC, KT88, KT90, 6550). The driver stage is an SRPP using a 12SL7 tube. For the amp shown above, the output stage is a Class A UL SIPP using Gold Lion KT88 vacuum tubes. LM317 Regulators are used to provide the cathode CCS.
