Selling my custom built EL34/KT77/6L6GC/6P3S-E Single ended class A Triode/Ultralienar tube Amplifier. I have built this amp myself based on a Douk Audio chassis but with some important design improvements and better components as follows: - Audiophile coupling caps: Jantzen Audio superior Z 1200V - ELNA Cerafine cathode bypass caps and Vishay filter caps - Takman(Japan) and Allen Bradley carbon composite resistors in audio critical circuit spots - Triode / Ultralinear switches (original design is only UL) - Cathode bias adjustment knobs with resistor networks in parallel (inexistent in the original design) Adjustable bias allows for usage with a wide range of tubes. It is thus a great start for tube rolling. The amp is offered with the following tubes: A pair of JJ KT77 power tubes A pair of 6P3S-E power tubes A pair of 6H8C preamp tubes 1X Svetlana 5U4G / 5C3S rectifier tube 1X 5C4S / 5Z4 rectifier tube Important:  The amp should not be power cycled while hot/warm to avoid cathode stripping and rectifier sparks in order to preserve the life of tubes. UL/Triode switching should be avoided during operation Bias switching during operation is okay in this configuration but should be avoided. Single ended triode amps are low power and highly recommended to be used with high sensitivity 90dB+ speakers Selling due to involvement in several other tube amp projects.

Bonjour, il s'agit la du premier intégré a transistors de la marque de 1967 avec un son tel un ampli a tube, il est dans un état exceptionnel ésthetiquement et parfaitement fonctionnel. Des fonctions unique comme la position Null est un mode de test, et est utilisée pour établir l'équilibre électrique exact entre les deux canaux stéréo. Contrairement au mode Mono, qui ajoute les signaux d'entrée (A + B) en les combinant en phase, le mode Null les combine hors phase pour faire soustraire les signaux les uns des autres (A – B). Ainsi, lorsque les signaux vers les deux canaux stéréo sont identiques et ont exactement le même volume, le résultat est une annulation presque parfaite, ou un "nul". Mais aussi une seule entrée phono à aimant mobile et de commandes de réglage de niveau. Ainsi, non seulement une large gamme de micros peut être adaptée, mais ils peuvent également être adaptés en niveau aux entrées de haut niveau de l'amplificateur, de sorte que le sélecteur d'entrée peut être commuté de source à source sans changement radical de volume. Et avec un jeu de niveau séparé pour chaque canal phono, les sorties de lecture peuvent être parfaitement égales. Une perle rare dans son carton d'origine avec tous ses documents et manuel schéma.  Hello, this is the first transistor integrated of the brand from 1967 with a sound like a tube amp, it is in exceptional condition aesthetically and perfectly functional. Unique functions like the Null position is a test mode, and is used to establish the exact electrical balance between the two stereo channels. Unlike Mono mode, which adds input signals (A + B) by combining them in phase, Null mode combines them out of phase to subtract the signals from each other (A - B). So when the signals to the two stereo channels are identical and have exactly the same volume, the result is almost perfect cancellation, or "zero". But also a single moving magnet phono input and level adjustment controls. So not only can a wide range of mics be matched, but they can also be level matched to high level amplifier inputs, so that the input selector can be switched from source to source without drastic change in volume. And with a separate level set for each phono channel, the playback outputs can be perfectly equal. A rare find in its original box with all its documents and diagram manual. Specifications: Power output: 50 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.25% Damping factor: 40 Input sensitivity: 2mV (MM), 200mV (line) Signal to noise ratio: 57dB (MM), 75dB (line)

Little jewel, one of the greatest headphones amplifiers ever, extremely rare on sale, in perfect working condition and aesthetics, almost like new. Trully impressive, addicting sound. Higly regarded by audiophiles, a true reference and a collectible item. Would loved to keep this one, I'm selling it reluctantly... Comes with original box and accessories, well packaged. Would consider posting it internationally but please, ask for a quote as the postage differs from country to country and the amount in the description is for European Union only, thanks. b'"' In terms of the criteria that I listen for in any amp, transparency, noise, dynamics and the ability to get me out of my head and into the music, Prime is well, prime. All in all, a seemingly impressive effort that covers all the bases.b'"' From Neil Gader's review in The Absolute Sound head-fi.org/threads/meridian-prime-headphone-amplifier-review.691392/ Headfonia: MERIDIAN PRIME - ENGLISH EXCELLENCE b'"'Does The Prime Live Up To The Meridian Name? First I tried the Prime as an Amp/Dac combo (with PSU) and I immediately loved the sound from this demo unit: Enormous Clarity, great detail retrieval from bass to treble, top precision and dynamic sound. All presented with just the right amount of air between the instruments. Musical and detailed sound with a superb flow. The Prime sounds fast and is neutrally tuned but the best solid state kind there is. Maybe it is just slightly forward sounding, but not that much. Bass is tight, goes deep, is well layered and has a lot of detail but doesn’t have the big body of say the Beyerdynamic A20 amplifier (but it has far better quality). The Prime is a linear tuned unit and I find the bass to be perfect (and that’s an understatement) with the Audeze and Hifiman headphones but more on those later. The Prime’s mids are slightly more forward sounding, especially the vocals, but they are not bright. Don’t get me wrong on that because they sound incredibly good: perfect separation, great timbre, heaps of detail but never over-analytical and always musical and dynamic. Treble is extended and detailed but never harsh sounding. I do like my treble and the Prime does a splendid job for my taste. Treble is on the same level as the mids and bass: clarity, detail and sparkle. The Prime’s sound stage is wide and deep with a perfect balance and 3-dimensionality. I fell in love with the Prime’s sound as a DAC/Amp unit. For me this is top audiophile sound.b'"' The Prime can also be used as a DAC and Pre Amp in combination with a power amp, headphone amp or active speakers. There is no disappointment here, the Meridian DAC delivers a stunning performance in combination with my desktop sized solid state and tube amps. I love a clear, detailed and neutral DAC with a huge sound stage. Who wouldn’t? Well this is one of those DACs I could live happily ever after with. It ads nothing to the sound, in a good way that is, and using it as a pre amp boosts the performance of your amplifier. headfonia.com/meridian-prime-english-excellence/ The Prime is a top-class headphone amplifier and a surprisingly talented stereo preamp. Meridian is a master at signal processing, so it’s no surprise to find ‘Analogue Spatial Processing’ on board the Prime. It’s a function designed to counteract the fact that stereo recordings are designed to be played over speakers, not headphones. ASP blends the left and right channels to varying degrees – there are three options – to try to create a more natural presentation. These features can often compromise clarity and focus to improve sound staging, but ASP sounds pretty convincing. The Prime also works well as a dedicated stereo preamp. It’s certainly right up there with some of the best preamps we’ve heard at around the £1000 mark. En savoir plus
