  • Conrad Johnson Classic 62 - 60w/ch stereo, vacuum-tube

    Conrad Johnson Classic 62 - 60w/ch stereo, vacuum-tube

    The conrad-johnson design team is committed to adapting the advances from our state-of-the-art pursuits to more affordable offerings accessible to a wider range of music lovers. This resolve is clearly evident in our new range of Classic amplifiers. Borrowing heavily on the technology of our flagship ART amplifier, the Classic amplifiers preserve the distinctive tonal character of individual instruments and voices, with each clearly located within the overall acoustical environment of the original recording. Musical transients are reproduced with realistic impact, but without artificial enhancement. Like their more costly siblings, the Classic amplifiers capture the emotional impact of the live event, never getting between the listener and the musical performance. There really is no mystery to our chosen path to outstanding musical performance: best results come from simple circuits executed with quality parts. The circuit design for the Classic amplifiers is about as simple as possible, employing just seven vacuum tubes in the Classic Sixty-Two. Single-ended triode voltage gain and inverter stages are coupled to an output stage comprised of a single pair of ultra-linear operated EL34 tubes for each channel. The Classic One-Twenty adds a second pair of output tubes to each channel to achieve twice the output power. Simple but highly effective discrete voltage regulators supply rock-solid stable DC voltage to the critical voltage gain and inverter stages. And speaking of simple, maintenance of the Classic amplifiers could hardly be easier: the owner need only make a simple bias adjustment using the built in bias indicators when installing fresh output tubes. The use of premium quality component parts is the other half of the conrad-johnson recipe for superior musicality. In this area as well, the Classic amplifiers are leaders in their class. Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene and polystyrene capacitors, chosen to achieve a high degree of temporal accuracy, are specified for both the audio cir¬cuits and the regulated plate voltage supplies for the input and inverter stages. The result is an exceptional range of dynamics – reproducing both subtle variations in level as well as dramatic loud crescendos. Our proprietary trans-spectral wide-bandwidth output transformers contribute importantly to the extended, “airy” highs that help distinguish the Classic amplifiers from ordinary tube amplifiers. The base model Classic amplifiers offer an ideal introduction to the joys of modern tube amplifiers, while the ease of use, low maintenance costs, and reliability will be a revelation for those who have only experienced “entry-level” tube gear. Those who wish to take the experience a step further will want to investigate the upgraded Classic Sixty-Two SE and Classic One-Twenty SE amplifiers. These special edition versions upgrade the output tubes to KT120s and incorporate CJD Teflon Capacitors and ultra high-performance metal foil resistors in strategic applications in the circuit. Any of the Classic amplifier models are sure to rekindle your passion for enjoying great music in your home. Learn More

  • Conrad Johnson Premier 11a

    Conrad Johnson Premier 11a

    Conrad Johnson Premier 11a We purchased this Premier 11a no tubes buy yourself some new ones and no need to worry about what would be in them Premier Eleven Vacuum Tube Amplifier Essentially a scaled down, stereo version of the Premier Eight, the Premier Eleven delivered 70 watts per channel from a single pair of 6550 output tubes. The Premier Eleven used only the finest component parts in all stages including the power supply. The power supply used only polypropylene and “cjd” polystyrene capacitors as opposed to the traditional deployment of electrolytics. The main storage reservoir used polypropylene capacitors with polystyrene shunts. The Eleven-A added a noise filter on the bias indicator circuit, first employed in the Premier Twelve. Features: 5-way binding post speaker connectors one pair of inputs two plate fuses power switch Replacement Tube Sets: RTPR11 or RTPR11XS V1 & V2: 5751 | V3 & V4: 6FQ7/6CG7 | V5-V8: 6550 Premier Eleven, Eleven-A: V5-V8: You could use kt120 tubes also without any modificaton but the cage will not fit because of the taller tube size. (I always thought they looked much better without the cages on anyway) Specifications: Power Output ­ Ultralinear Operation: 70 watts per channel RMS at 4, 8, or16 ohms both channels driven from 30Hz to 15kHz with no more than 1% THD or IMD. Power Output ­ Triode Operation: 30 watts per channel RMS at 4, 8, or16 ohms both channels driven from 30Hz to 15kHz with no more than 1.5% THD or IMD. Frequency Response: 20Hz to 20 kHz, +0, -.1 dB Input Sensitivity: 0.9 volts to rated power Hum & Noise: 96 dB below rated power Mechanical: Dimensions: 17.5W | 7.25H | 15D inches Weight: 48 lbs.

  • Audio Research VS110

    Audio Research VS110

    Audio Research VS110 2 available price is for each unused since 2014 in 11/2021 Given the enthusiastic response to the appearance and sonic peformance of the VS55, you will be happy to know that a more powerful version of this remarkable amplifier is now available: the VS110, rated at 100 WPC. This brings vacuum-tube musicality as only Audio Research can do it to a new power level and price. The chassis, circuit layout and feature set of the VS110 are almost identical to the VS55, but scaled up to accomodate the greater power output. The chassis itself measures 17 ½" W by 19" D, and features an anodized, natural-finish top plate labeled with tube location/type, output-tube bias access points and the inset Audio Research logo. The chassis front holds a rocker-style power switch and green LED "on" indicator. The chassis rear provides the 0-4-8 ohm 5-way binding posts, voltmeter test points for setting bias, a 12V in/out trigger and a detachable 14-gauge A.C. line cord with IEC socket. There are two matched pair of 6550C output tubes in each channel, fed by two 6NIP triode driver/followers, which in turn are fed by a single 6NIP input tube. Storage capacity of the bulk power supply is double that of the VS55 and uses the same type of fast, low-ESR Nichicon® capacitors. The simplicity and purity of the audio circuit is a proven performer, but now it can deliver more power for larger speakers in larger rooms. Like the VS55, the VS110 ships in one color /chassis configuration, black with natural anodized top plate. A perforated cage-type cover is optional, and must be ordered as a separate item. The sonic signature of the VS110 is very much like that of the VS55, but with more robust dynamics, greater bass impact and power, and a larger soundstage. With so much similarity between these two amplifiers, choosing the right amplifier is simple. The look, the feature set, the circuit types are identical: it is simply a question of how much power you need or want. The VS110 combines classic tube-amplifier appeal with robust power, genuine musicality and solid value. And don't forget Audio Research's unmatched record for long-term product support - a key measure of keeping customers satisfied, decade after decade. POWER OUTPUT 100 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 100 watts, below .05% at 1 watt. Approximate actual power available at "clipping": 120 watts (1kHz) (Note that the actual RMS power output is dependent upon both line voltage and "condition" ie: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)

    Top of the line. Cary 211M mono amplifier, used pair in excellent condition original crates and double boxes. Photos are without tubes but you get those packed separately. It is well known that using monoblock amplifiers, as opposed to both channels together as a stereo chassis, is the best way to get powerful and lifelike music. By using separate power supplies that can be much more massive, each amplifier can have more dynamic power and be quieter. Keeping two separate amplifiers also makes any inter-channel crosstalk in the amplifiers impossible, so separation is better, meaning your soundstage and musical imaging will be larger and more well-defined. The simple act of separating the two channels provides a lot of distinct advantages, but also increases the investment because of needing to double up on power supplies and chassis parts. Learn More
