I've had this Zenith 3L01 console amp laying around for years now and decided to play with it. It uses a 7695 tube for the outputs, and a 12AX7 input. The 7695 tube is used in series wired direct line voltage applications. The sound from the stock amp wasn't really good so I remounted the output transformers and tubes on a Hammond chassis and lashed it together with the RH-84 circuit. Now it sounds really good! The schematic below is the power supply, the rest of the circuit is standard RH-84.
