I300

About the I300

The Jadis I300 is a French-made, line-level tube integrated amplifier built around four directly heated 300B output tubes in a push-pull, pure Class A configuration without global negative feedback. It uses automatic bias, separate power-supply circuits for the amplifier stages and 300B heaters, and Jadis-designed EI M6X power and double-CV38 output transformers. The amplifier includes five line inputs, a bypass output, speaker outputs, balance and volume controls, and a remote control. It does not include an internal phono stage or DAC. Published sources differ on weight and power-consumption figures; Jadis’s current product information lists 39 kg and 200 VA, while some reviews report approximately 30–40 kg and up to 300 VA. No reliable evidence indicates that the I300 has been discontinued; it remains listed by Jadis and specialist dealers.
