They Can Only Be Heard. A specification sheet will tell you that this amplifier produces ten watts per channel into a four or eight ohm load, that total harmonic distortion measures one percent at one kilohertz, and that signal to noise sits at 88 decibels. None of that explains why a single-ended Class A circuit with two EL34 power tubes makes a human voice sound like it is standing in the room, and the people who buy this kind of amplifier stopped needing it explained some time ago.\u003c\/p\u003e\n\u003cp\u003eThe topology is deliberately old fashioned where it matters. Class A single-ended operation keeps the output device conducting through the entire waveform, which removes the crossover distortion that push-pull designs introduce and is the reason the midrange sounds unbroken. Five tubes do the work: a 5Z3P or 5U4G rectifier, two 6SN7GT preamp valves, and two EL34C power valves, all self-biased so the owner is not adjusting bias with a meter. The output transformers are wound on Japanese Z11 0.35mm laminations, the coupling capacitors are German electrodeless and Philips cathode types, the resistors are ring precision metal film, and the wiring is hand soldered point to point rather than run across a printed board.\u003c\/p\u003e\n\u003cp\u003eThe physical build follows the same logic. A steel chassis with a backplane carries pure copper RCA inputs and pure copper speaker terminals, so the owner can use banana plugs, spade connectors or bare wire without an adapter. Frequency response runs from 20Hz to 25kHz, input sensitivity from 500mV to 2000mV, input impedance is 100Kohm, and the unit draws 105 watts from a 110 to 120 volt or 220 to 240 volt supply at 50 or 60Hz. It weighs 10 kilograms across 380 by 160 by 230 millimetres, which is heavy enough to stay put on a shelf and compact enough to live there. Speakers between 10 and 100 watts with an impedance of 4 or 8 ohms are the correct match.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eTen honest watts, in a room that is listening.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr style=\"margin: 28px 0;

Vocal and acoustic listening is the stated strength, which suits a small room, a near-field desk setup, or a listening chair that is occupied for an hour at a time rather than all evening. A turntable and a phono stage, or a network streamer with a clean analogue output, feed the RCA inputs directly. Headphone listeners use the speaker taps with an adapter. Because the amplifier runs at ten watts per channel, the speakers matter more than the source: high efficiency bookshelf or small floorstanding models between 10 and 100 watts at 4 or 8 ohms will be driven comfortably, while low sensitivity speakers in a large room will run out of headroom. Buyers keeping a second system in a study or a bedroom are the most satisfied group.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr style=\"margin: 28px 0; border: 0; border-top: 1px solid #e6e6e6;\"\u003e\n\u003cdiv class=\"product-faq\"\u003e\n\u003ch3 style=\"font-size: 19px; margin: 0 0 16px;\"\u003eListening Questions\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom: 16px;\"\u003e\n\u003cp style=\"margin: 0 0 6px; font-weight: 600; color: #1a3a5c;\"\u003eQ: Do I need to set the bias myself?\u003c\/p\u003e\n\u003cp style=\"margin: 0; color: #3a3a3a;\"\u003eA: No. The amplifier is self-biasing, so the valves settle without a meter or a trim procedure.
