Oilily A300B MK 300B Tube Amplifier, Class A Single-Ended Stereo, Silver | 300BX2 Single-Ended Class A Tube Integrated Amplifier, 8W+8W (8Ω), 4-16Ω Taps, Headphone Out, Remote, Dual Meters

• Premium Tube Configuration: A pair of 300B output tubes with a 5AR4 rectifier, driven by 6N11 and 6N6 in the voltage stage, running pure Class A single-ended. This MK version adds two line inputs (LINE1 and LINE2), a PRE-IN power-amplifier input, and a remote control.
• Transformers & Monitoring: 8 W + 8 W output driven by a custom square power transformer and two wide-response EI output transformers; dual front-panel gauges show output level and tube current in real time, so you can see the amplifier working.
• Rated Output & Break-In: 8 W + 8 W into 8 ohms at 5% THD or less, from a pair of 300B tubes in pure Class A single-ended - the classic 300B topology, which trades raw wattage for tonal purity. Like all tube amplifiers, it needs playing time: expect roughly 80 hours at moderate volume before the sound fully settles, with the soundstage opening up around 50 hours. This is normal tube burn-in, not a defect.
• Speaker & Headphone Outputs: Speaker terminals accept 4, 8, and 16 ohm speakers. The front-panel 6.5mm (1/4") headphone jack engages automatically when a plug is inserted, switching the amplifier to headphone mode. It drives headphones from 8 to 300 ohms, driven by the same 300B output tubes.
• Blue Accent Light: A soft blue accent light sits beneath the three front tubes and glows whenever the amplifier is powered on. It is part of the tube-stage illumination design and is always on during operation.
• Warranty and support Main Unit (Amplifier): A 1-Year Limited Warranty covering defects in materials and workmanship under normal use. Vacuum Tubes: A 3-Month Limited Warranty from the date of delivery. Vacuum tubes are consumable components with a finite lifespan. Start and end dates: The warranty period begins on the date of original purchase or delivery and expires one year (main unit) or three months (vacuum tubes) from that date.
