A PseudoAtarashi 211 Single_Ended Amplifier

Photo1 The Amplifier Chassis with El34s

Back in 1971 Mr. Atarashi conceived a Single_Ended amplifier with an EL34/6CA7 in the driver stage. The output tube was a 845 and the input one an EF86 in pseudo-triode connection. The output transformer was isolated from power supply by an L-C coupling.

This proposal indeed has a 211 as output tube and an air gap O.T. to match the load.
