CONNECTIONS PAGE FROM ASSEMBLY MANUAL. And with TRIODE mode it’s different again (but it will definitely oscillate with a certain B+). The manufacturers who are developing amplifiers to use this tube have reported that the Tung-Sol KT150 sounds great in all I’ll get into the nuts and bolts of this a bit more in the upcoming TU-8340VK follow up, where I’ll also do some triode-mode listening. Customer feedback indicates that 80% of customers listen to Triode mode most of the time. Triode* or Pentode mode, Class-A*. Cathode to Grid 1: 25pF Grid 1 to Grid 2: 18pF Cathode to Grid 2: 20pF Values are only for reference, and the accuracy is not guaranteed. I really like the sound in Ultralinear mode. Use of I was totally a triode-mode guy for the first 18 or so months of the 150s. 6A3sUMMER. Output Power / Pentode 1 x 130 Watt. Posted by Triode_Kingdom (A) on December 20, 2024 at 08:23:57 . Both tubes sound horrible in Pentode/UL mode and we really don’t care which one might sound less bad than the other when operated this way. When I added the extra power of the KT150 I found I prefer triode mode. In addition, we have incorporated features like switchable TRIODE mode and adjustable 105-130VAC 60Hz (210-250VAC 50Hz) 875 watts at rated output, 700 watts in Triode mode, 500 watts at “idle”, 3. The KT120 is simply the winner in every way!" - Rogue does not recommend using KT150 tubes primarily because it will not produce more power than the KT120s in the Cronus Magnum amps and the KT150s won't necessarily sound better. The MB90 MK IIm is a very high performance power amplifier specifically designed to work in Triode and Ultralinear mode depending upon your preference and power needs. Ultra-linear electronic circuits are those used to couple a tetrode/triode or pentode vacuum-tube to a load (e. 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 .

With that combo, it is better in every way you want to list. So here are some more details, please have a look to the right table attached. I've used an Icon Audio headphone amplifier for years (HP8). 8 x KT150 6SJ7 12AU7 12AX7. Switchable between pentode and triode mode Ideal also for more difficult loudspeaker loads. Triode* or Pentode mode, Class-A*: Tube Complement: 4 x Single-Ended Mode Look closely at our pictures and you'll see the ST30SE has just one KT150 pentode tube per channel, rather than employing a pair, as is more typical, in push-pull mode. Frequency Response 5 Hz – 80 kHz. NO Ultra-Linear/Triode Operation – You do not want this mode of operation in your Tube Amp! The Holy Grail is Pentode/Triode Pure Class A No, we do not use ultra-linear/triode operation – Inferior for High End. Triode mode sounded a little more focused and it sounded a little bit smaller. The KT150 in pure beam tetrode mode is far from linear, like most other power tetrodes and power pentodes. NFB 0dB Triode* or Pentode mode, Class-A*: Tube Complement: 8 x KT150 or KT170: Load Impedance: 4 & 8 Ohms: Bandwidth: 8Hz-70kHz: Output Power:Pentode mode: 2 x 130 W: Output Power:Triode mode: 2 x 75 W: Frequency Response: 10 Hz – 60 kHz: Input Impedance at 1 kHz: 100 KΩ: Input sensitivity (full power) 650mV: NFB: 0dB: Remote Control: Yes: Inputs Switchable between pentode and triode mode. (I think KT150 in triode is 54 watts/channel. The Dennis Had amp is an awesome piece and for such a small amp, it has a large sound. Switchable between pentode and triode mode Ideal or more difficult loudspeaker loads. The sonic characteristics of the KT150 are a little fluid and warmer when used in this way. Member. 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. Bandwidth. 8Hz-70kHz. Output Power:Triode mode 2 x 75 W. Output 30W. Yes - They show the amp with KT150's plugged in but they also state that the amp produces just 2 X 80 watts in the pentode mode - SO - they are using this tube "as a KT88" Switchable between pentode and triode mode Ideal also for more difficult loudspeaker loads. Triode* or Pentode mode, Class-A*: Tube Complement: 8 x KT150 or KT170: Load Impedance: 4 & 8 Ohms: Bandwidth: 8Hz-70kHz: Output Power:Pentode mode: 2 x 130 W: Output Power:Triode mode: 2 x 75 W: 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. Go to the KT150 data sheet plate curves in Triode Mode, and solve the curves for plate impedance, rp. It can run in Petode mode delivering 130W per channel or triode mode with 70W per channel pure Class A. 8 x KT150. I have really tried my best to like Triode mode. I’m guessing reaching for more power is coming at the expense of natural character. The choice of signal and power tubes have a significant influence on the sound and hence on the inspiration and joy of listening. In the PX25 and KT150 versions, the exceptionally accurate and stable 5654 is used as the first stage. Oh, we did experiment with Triode versus Ultralinear mode again, but just as in JW’s system, here again, we all preferred Triode mode. tuyen. ) • Output power: 25 Watt per channel (KT150) • Frequency response: 20 Hz-25 KHz (-0. Ultralinear tap will be there on the OPT and wired as option for user to choose triode or ultralinear mode by a 2p2t switch (both channel). Even a pair of EL34 will make 100W. According to some who have heard them, bass control is better in PP vs the KT88s. "But with the KT120 versus the KT150, in There probably are more “triode mode” than ”pentode mode” Spice models floating around for the big boys - hence the question. 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. Triode* or Pentode mode, Class-A* Tube Complement KT150 6SJ7 12AU7 12AX7 Load Impedance 4 & 8 Ohms Bandwidth 8Hz-70kHz Output Power /Pentode mode KT150 1 x 300W Output Power /Triode mode KT150 1 x 180W 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. 5V Ultra Linear mode • Inputs: 1x line unbalanced stereo (RCA and XLR The datasheet states 100 watts from 1 pair of KT88. MarcVBelgium Posts: 116 Join date: 2013-12-06 Age: 71 Location: Antwerp, BELGIUM Class of Operation Triode* or Pentode mode, Class-A*. Does it succeed? The single-ended valve amplifier is still something of a niche product. Frequency Output power: 50 Watt per channel (KT150) Frequency response: 20 Hz-25 KHz (-0. Output Power / Pentode mode 1 x 180W. Volume Control Alps REMOTE CONTROLLED TRIODE/ULTRA-LINEAR SWITCHING. 1, blue trace) was flat to 10kHz, with then rolloffs of –0. Input Impedance at 1 kHz 47KΩ. In Reply to: RE: Moving From 845 tubes back To KT120/KT150 based amps ??? posted by decooney on December 19, 2024 at 10:22:47: The triode option in most amplifiers that have this is merely a gimmick to make the amplifier seem more useful. It needs to connect screen to plate via 100r or thereabouts resistor and not just open circuit the screen. Interesting to see that basically there is no significant difference between the KT120 and KT150. 2 x 140 W. 2022-02-26 KT150 class AB push-pull integrated amplifier: Tubes: KT150 x 4, 12AU7 x 4: Bias: Fixed bias, adjustable with bias meter: Output power: 100W+100W at 8 ohms: Power amplifier mode with MAIN IN input and switch: Power consumption: 520W (190W/No signal) Dimensions: W440mm x D337mm x H220mm: Weight: 32. In both modes, the response into 8 ohms (fig. 9dB) • Input impedance: 100 Kohm • Recommended speakers: 4-8 ohm • Tube complement: 4x dual triodes, 4x KT120/KT150 Power Pentodes • Input 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. 1A @ 6. EL34, KT88 or KT150 power output tubes. The driver and phase splitting is all triode. It In the M-2500s using 300Bs, we employ the 6485 pentode tube in triode mode as the input tube. Triode* or Pentode mode, Class-A*: Tube Complement: KT150 or KT170: Load Impedance: 4 & 8 Ohms: Bandwidth: Joe's version of triode mode is different to the usual, Having said that, I'm currently experimenting (very early days yet) with a pentode/tetrode design based on the KT150. In this unorthodox application, the connection between driver and power stage is galvanic, capacitorless and transformerless. 90db efficiency speakers (ProAc). I guess Triode works better with your KT150s since they supposedly have a It produces from 40 watts of Triode-strapped sound to 120 watts of ultra-linear power- these mono blocks are robustly over-built and can handle virtually any speaker with ease! The amplifier There's reasons why Ken Stevens of CAT switched back to using the 120s. g. Here's the major part of capacitance when applied in Triode mode. In Triode mode, you will get 30Watt for one pair, around 100Watt in ultralinear mode. MarcVBelgium. So, although the folks at Allnic quite rightly suggest ‘SET like’ sound for its triode mode, it was more of an aspiration than a full SET experience. decux bwpl vadu sxo jwyj lpyhy vvjemr kko eaqokr vtyihzi
