The power amplifiers used in Enyo are a completely new design based on our research over the last 10 years, with a 3-stage fully differential architecture. The output stage uses the rare arrangement of cathode feedback while retaining the usual ultra-linear connection of the pentodes. This required the design of a special output transformer wound on double C-core GOSS. Driving this output stage called for the development of a special front end circuit accommodating positive grid swing. DC-coupled tubes are rare but Enyo uses only a single capacitor in the signal path.
The input and driver tubes used are our favourite 6n6p. While the output stage duty goes to the GU50. The Gu50 tube is based on Telefunken LS50 but made by the Soviets for the radio communication in the MIG planes. This is evident by looking at the socket locking the tube from falling out due to heavy vibration.
Luckily they made a lot of them and the tube is available worldwide for a very reasonable cost for the quality it offers. The power supply for the amplifier uses choke filtering to guarantee pitch black backgrounds and freedom from power supply modulation. Those are features rarely seen in anything other than top quality tube mono blocks.
