Single Ended A2 6A3/300B
This amp has great specs, produces twice the power from your favorite tube and is simple to build. But you will need to decide which power transformer to use, both have identical performance but one runs cooler than the other because of the laminations. Then select which output transformer you’d like, our standard copper wound or the new PSSS which gives silver performance at a fraction of solid silver price. Read Jack’s comments at www.electra-print.com->Tech Blog->Spring 2007->Class A2 Operation for a description of this new transformer. You can find a list of the Electra Print transformers needed to build this amp below the schematics.
