Ninety watts per channel of pure tube power, from four KT88 output tubes in push-pull.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eIt borrows its circuitry from Rogue's more advanced designs rather than being engineered down to a price. The signal paths are short, the noise design is careful, and the components are the precision parts you would expect further up the range.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAn oversized linear power supply sits behind all of it, storing the energy that dynamic passages demand. That supply is usually the first thing cut from an affordable tube amp, and its absence is the first thing you hear when the music gets loud.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eInside the Chassis\u003c\/h2\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eAn ultralinear and triode switch lets you choose the amp's character. Ultralinear gives you slam. Pure triode gives you the smoothness that tubes get bought for in the first place. The switch is on the back, so you can try both.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eYou also pick the transformer tap, 4 ohm or 8. Matching it to your speakers is what separates a tube amp that controls a speaker from one that merely drives it.\u003c\/p\u003e\n\n\u003cp style=\"margin:0 0 0.9em 0;line-height:1.55;\"\u003eThe tube complement is four KT88 output tubes with two 12AX7 and two 12AU7 in the small-signal stages. Bandwidth runs 20Hz to 30kHz. Slow-start turn-on sequencing protects the tubes, the board is heavy two-ounce copper, and the faceplate is machined aluminum. It measures 18 inches wide, 17 deep and 6.75 high.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:1.25em;margin:1.4em 0 0.35em 0;font-weight:600;\"\u003eWho Is This Amplifier Best For?\u003c\/h2\u003e\n\n\u003cul style=\"margin:0 0 0.9em 0;padding-left:1.4em;line-height:1.6;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou want real tube power on a budget\u003c\/strong\u003e — one hundred watts per channel from four KT88s is genuine tube power, not a small amplifier with a valve in the input stage for flavor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou want to choose your own sound\u003c\/strong\u003e — the ultralinear and triode switch changes the amplifier's character from the back panel, so you set it to your speakers and your ears after it arrives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYour speakers are a particular load\u003c\/strong\u003e — selectable 4 and 8 ohm taps let you match the output transformer, which is what keeps a tube amp controlled rather than merely loud.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou are buying your first tube amplifier\u003c\/strong\u003e — slow-start sequencing protects the tubes at switch-on, and the KT88 is a current-production type that is straightforward to replace when the time comes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou do not own a preamplifier yet\u003c\/strong\u003e — the Atlas Magnum III is a power amplifier, with no volume control and no input switching.
