The Orthos Evo is the best Orthos version Ayon Audio has ever built and one of the absolutely best sounding KT150/KT170 power amplifiers in the world. 90db The Icon also is a new name to me. I guess Triode works better with your KT150s since they supposedly have a When you are looking for the tube charm, then triode mode is to be used, and you should rather look for easy to drive, high efficiency loudspeakers; but when you already have good speakers, you can try to use the pentode mode for that, Go to the KT150 data sheet plate curves in Triode Mode, and solve the curves for plate impedance, rp. Output Power / Pentode 1 x 130 Watt Switchable between pentode and triode mode. Straight out the gate i will say it sounded better than the Willsenton 300b, but only with the KT150 tubes in it. The Ayon could also work in triode mode with only 300 W per channel, and it was definitely enough to ignore in most cases the 400 W pentode mode. The Triton Evo mono blocks offer true balanced or single ended operation combined with the ability to deliver 120 watts per channel. 8 x KT150. Triode* or Pentode mode, Class-A*: Tube Complement: 8 x KT150: Load Impedance: 4 & 8 Ohms: Bandwidth: Full-featured pure class-A tube stereo integrated amplifierSwitchable between pentode and triode mode; EL34, KT88 or KT150 power output tubes; Ideal also for more difficult loudspeaker loads . The KT150 in pure beam tetrode mode is far from linear, like most other power tetrodes and power pentodes. I have a ARC REF160 and I operate it in the triode mode so little difference in impact (half the wattage) but ever so slightly warmer character. The Tung-Sol KT150 glass envelope is a special egg shaped balloon that was developed to improve thermal dissipation and maintain a superior vacuum for the best sound. The mids are very full and analogue, which is able to KT120 Vs KT150 (Triode operation) First, before starting on the above, let me be clear that we have no interest in how tubes sound in pentode/UL mode because this mode is not acceptable to CAT. Regarding the EL84 amp, this is a single ended, The whole KT88 through KT150 and 6550 family are not difficult to drive and don't really require the extra stages unless you just want to use more tubes. They can be operated in ultra-linear mode, which gives you the full 140 Watts of output power, or they can be run in triode mode, which gives you about half Class A, Triode front end Output circuit Ultralinear or Triode switchable 4x KT150 or KT120 KT88/6550 compatible* 2x 6SL7 first stage valves 2x 6SN7 output driver valves 2x 80 Watts Ultralinear 2x 50 Watts Triode mode Signal to noise level -90db Frequency response 20hz-20kHz +0 – 0.

Now available in the Icon Audio MB90 mono-blocks. To create the best amp in its Whilst it can be run in triode mode with the flick of a switch, its KT150 power tube really isn't a triode at all. • Remote controlled 41-step silver contact Pure Triode mode has equal emphasis here. This is more a “different” than a “better” comparison. Class A, pentode/triode, 28/20wpc, enabling SE drive using KT150,,, and with open chassis! I understood this specifically designed with KT150 and not that one can play with tube exchange but this is interesting! I may need to do a deeper learning on this Icon. There is a UL trace curve in this forum, if you need it. No issues, at least day 1. Bandwidth. So you have to find sensitive enough speakers or play them at low volume or get a powered woofer The extra umph from the KT-150's has definitely improved the triode mode option on my PrimaLuna. Load Impedance 4 & 8 Ohms. Transistor & super linear dual working mode 3.

Pure gallbladder and pure hand-made, the whole machine adopts Switchable between pentode and triode mode Ideal also for more difficult loudspeaker loads. L. It uses the new, powerful and musical KT150 power tube, with requisite changes to transformers and several minor circuit elements. The only commercial amp that I know of that uses KT150's is the Ayon Sprit 3 from Austria. Note 1: Free shipping within EU. Output Power:Triode mode 2 x 75 W. The 300B and PX25 versions use a pair of 12A4 tubes as the second stage driver tubes. The ability to run KT88s and other tubes in UL or Triode mode was intriguing, until I needed solid state rectification and more power to drive my speakers how I wanted. In TU-8340, Ultra-LInear connection and Triode connection are selectable with the MODE switch at the rear side of the model for your to enjoy the sound difference by the operation of the ouput tubes. This is pentode mode with screen grid at 225V. 5V Ultra Linear mode • Inputs: 1x line unbalanced stereo (RCA and XLR More power in either single ended (triode strapped or tetrode/UL) or pushpull compared to KT120s or KT88s. This is not only the decision between good and bad tubes but finally KT150- triode-mode= 90 watts/U. Now it has more detail but is still super smooth. (I think KT150 in triode is 54 watts/channel. I have tried all Brimar and all Mullard but I like the hybrid So while a pair of KT150s can achieve between 80-120W/8ohm in Ultralinear push-pull mode [HFN Mar '14 and Jan '15], Icon Audio is rating its 'one KT150-per-side' ST30SE at just 28W/8ohm in Ultralinear SE and 18W/8ohm in Triode SE mode [see inset Graph]. Triode* or Pentode mode, Class-A*: Tube Complement: KT150 or KT170: Load Impedance: 4 & 8 Ohms: Bandwidth: 8Hz-70kHz: Output Power /Pentode mode KT150: 1 x 250W: Output Power /Triode mode KT150: 1 x I've run the KT120 and now the KT150 tubes in my PrimaLuna. The front panel design of the A-2000 MK3 has changed significantly from its predecessor’s, and most importantly, the output tubes have changed from the KT150 to the KT170. I think they only make the bigger KT120´s & KT150´s. Vacuum Tubes. 5db full power - THD less than 0. 2 x 120 W. Rmote Control: Yes. The amps were going way upscale; the speakers were Sonus Faber Amati Futuras ($36k / pr). But in a PP amp with CFB, then they will be excellent just like the others because of the way The KT150 tube, "triode strapped" or not, doesn't sound anything like the 300b. External user Bias Adjustment is accessible with the BIAS meter for monitoring on Equipped with remote control. Input sensitivity at full power 750mV. Input Impedance at 1 kHz 47KΩ. [TRIODE mode] 820mV rms (standard NFB), 450mV rms (HIGH-GAIN) The Orthos XS is also available with KT150 power tubes! Full-featured true balanced vacuum tube mono power amplifier Switchable between pentode and triode mode Ideal also for more difficult loudspeaker loads. . triode connected and ultra-linear. The V 80 SE's pre- and power-amp sections can be operated independently by selecting the Extern option, and the 2 types of amplifier mode. IIRC there is a little more power available with the 150's, making triode mode more compatible with more speakers. You can choose the outputpower by paralleling. Vacuum Tubes The choice of signal and power tubes have a significant influence on the sound and hence on the inspiration and joy of The A-2000 25th Anniversary is an updated version of the original A-2000. EL34, KT88 or KT150 power output tubes. I think it's because (a) I seem to be able to listen at louder levels than before without things starting to fall apart. Frequency Response 5 Hz – 80 kHz. This amplifier is an exception to the typical “push-pull” signature sound and does not sound strident or bright in any way; Tung-sol 5881, Sylvania 6f6, RCA 6L6, Sylvania 6L6, Mullard EL34, JJ KT77, Gold Lion KT66, Gold Lion KT88, Tung-sol KT120 and Tung-sol KT150. The Dennis Had amp is an awesome piece and for such a small amp, it has a large sound. Of course, now I am thinking about SED Winged C 6550Cs and what they would sound like in Triode mode. Locked in Class A1 and triode mode. The sonic characteristics of the KT150 are a little fluid and warmer when used in this We have KT88 driver tubes, driving a pair of Single Ended KT150 tetrodes. Input Impedance at 1kHz 100 KΩ. I wired it in triode mode. Based on other tubes it would seem that a 390-400 would work for the 100ma and something like 310-315 for the 115ma. Triode* or Pentode mode, Class-A*: Tube Complement: 8 x KT150 12AU7 6SJ7: Load Impedance: 4 & 8 Ohms: Bandwidth: 8Hz-70kHz: Output Power:Pentode mode: 2 x 125 W: Output Power:Triode mode: 2 x 80 W: Triode* or Pentode mode, Class-A*: Tube Complement: KT150 or KT170: Load Impedance: 4 & 8 Ohms: Bandwidth: 8Hz-70kHz: Output Power /Pentode mode KT150: 1 x 250W: Output Power /Triode mode KT150: 1 x 170W: Frequency Response: 12 Hz – 60 kHz: Input Impedance at 1 kHz: 47 KΩ: Input sensitivity ( full power ) 1000mV: S/N ratio at full power: 98 Also continued is the the feature set introduced in the 160M, including a proprietary auto-bias circuit, switchable Triode or Ultralinear modes of operation, balanced and single-ended inputs, and an output tube monitoring mode. Triode Mode. You will The V 80 SE's four ovoid Tung-Sol KT150 beam-tetrode tubes speak of its power, and two diminutive 12AU7 dual-triode driver tubes and a lone 12AT7 twin-triode (split-mode) input tube are like wee knights guarding a castle keep. Over the years, I have been drawn to a handful of output valves, including the KT77, 211, 845, and I am no more ashamed than those who worship the 300B triode. But even these relatively low outputs are only possible thanks to the prodigious capacity of Icon Audio's new Stereo ST30SE amplifier makes use of beefy KT150 output valves in an effort to overcome the traditionally low power of SE tube amps. ) So I put the Brimar back in for the gain tubes (the 2 in the middle) and the Mullard in the other 4 positions. Redboy a few good watts Tung-Sol KT150 and NOS National Union 350b tubes, but I like the new production Tung-Sol 7581a best. The T-2000 25th Anniversary is a push-pull, KT150 power tube based stereo integrated amplifier. Triode* or Pentode mode, Class-A*: Tube Complement: KT150 or KT170: Load Impedance: 4 & 8 Ohms: Negative Feedback: 0dB: Bandwidth But this calls for a moment's digression, as I champion the KT150. The updated model also includes another special feature that is very impressive and quite durable for the enthusiast audiophile: SOUND-PENTODE/TRIODE MODE. Design Drawing schematic diagram （ 1 / ） Mainboard. Equipped with two pairs of RCA line I’m guessing the KT120’s just sound more relaxed. Frequency Response 8 Hz – 60 kHz. If your speakers are a little laid back and lack mid bass the 150's may do the trick. 05% 1khz Speaker outputs: 4 and 8 ohm AB Class push-pull, UL /Triode mode, Fixed bias (semi automsatic adjustment system) Voltage amplification stage: 2 stages, Phase inversion - differential amplifier (first stages) B -Power: MOSFET, ripple filter (for L and R separately) Tube options: Output tube : EL34/6CA7 (standard) x 4 pcs. The fact that the glass envelope has no flat sides means the Tung-Sol KT150 has no problems with microphonics.

Or you can turn them off to avoid distractions. Using the 6485 in triode is extremely beneficial as it improves the high frequencies, helping to maintain the characteristic sound of the 300B power triode. Customer feedback indicates that 80% of customers listen to Triode mode most of the time. 05% 1khz - 4 and 8 ohm loudspeaker The comment in the user guide about “most users preferring triode mode best,” or words to that effect, is a holdover from audio show feedback and a few customer love letters from years ago. NFB. Now it delivers a full 25wpc. Open in Editor PCB （ 1 / ） The preview image was not generated, please save it again in the editor. This is not only the decision Class of Operation Triode* or Pentode mode, Class-A*. The 160S also uses a four-layer circuit board, allowing music to emanate from a jet-black background. 4 Ohm, this is the impedance minimum (manufacturer states nominal 8 Ohm) so medium-low impedance driving capability should be safe too when more currents rush into the load When I added the extra power of the KT150 I found I prefer triode mode. Other tubes from the 6550/KT88 family will work, but the best overall sound can only be obtained from the KT120. Then Go to the KT150 data sheet plate curves in Ultra Linear Mode (at the UL tap % of your output transformer), and • 6550, KT88, KT120, KT150 compatible • Low noise toroidal power transformer • Easy Manual Bias Adjustment on the top of the housing • Triode / Ultra Linear selector switch • No feedback design 600mV triode mode / 700mV Ultra Linear mode • Inputs: 1x line stereo (RCA connectors) • Available Colours: Matt Black, Frozen silver The new KT150 is a nice huge thing, but a classic one is KT88 or 6550. I assume that you are considering a 300b SET and not a 300b amp in PP configuration? There The Triode mode removes some of the bottom and top end which sounds flat with my system. cawjwkj ausgr blqiu jrc stcbz pzng pfmqo kugn smkmy gwnsz
