The KT170 has a different shape and is larger than the KT150, and the KT170’s plate loss, which is used to measure the output, has increased from 70W to 85W. Straight out the gate i will say it sounded better than the Willsenton 300b, but only with the KT150 tubes in it. Locked in Class A1 and triode mode. Then Go to the KT150 data sheet plate curves in Ultra Linear Mode (at the UL tap % of your output transformer), and Oscillation starts around 395 Volt. I’m guessing reaching for more power is coming at the expense of natural character. I was asked what cathode resistor I would use for 100 and 115 ma with a anode voltage of 400. TUBES NOT INCLUDED In this amplifier, the bias condition is kept at an optimal level for the output tubes installed without a complicated bias adjustment by "Active Automatic Bias Adjustment System".

Other tubes from the 6550/KT88 family will work, The Bruiser can be connected in UltraLinear Mode for more power, but triode operation provides the cleanest, most musical But this calls for a moment's digression, as I champion the KT150. Read the latest review by Hi Fi News. 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. The sound of the amplifier throughout its power range is warm, clear, and transparent, an excellent choice for driving open baffle speakers. 6dB at 20kHz and –3dB at 50kHz, which correlate with the slightly lengthened risetimes with the amplifier's reproduction of a 10kHz squarewave into 8 . L. Class of Operation Triode* or Pentode mode, Class-A*. MarcVBelgium Posts: 116 Join date: 2013-12-06 Age: 71 Location: Antwerp, BELGIUM Class of Operation Triode* or Pentode mode, Class-A*. Frequency Response 5 Hz – 80 kHz. 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. Now in its fourth incarnation the ST60 has been upgraded each time to make it one of the finest high power integrated amplifier available. Incorporating our own “LDT” low distortion tertiary transformers. 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. In addition, four Tung-Sol KT150 or four Tung-Sol KT120 tubes are used as high-performance output stage tubes. I’m guessing the KT120’s just sound more relaxed. Triode* or Pentode mode, Class-A*: Tube Complement: 8 x KT150: Load Impedance: 4 & 8 Ohms: Bandwidth: 8Hz-70kHz / -3dB: Output Power:Pentode mode: 2 x 125 W: Output Power:Triode mode: 2 x 80 W: Capacitance between electrodes were not menthoned in the datasheet. Load Impedance. 8kg: Accessories: Switchable between pentode and triode mode. The choice of signal and power tubes have a significant influence on the sound and hence on the inspiration and joy of listening. All else being equal, triode mode needs different feedback and The Triode mode removes some of the bottom and top end which sounds flat with my system. saki70. The glass of the new KT120 valve is 12mm higher than a KT88, either pentode Ultralinear, or pure triode mode, using the excellent KT120/KT150 valves in fixed bias mode. Shipping price to any other country is an estimate. 2). Project Author: Joined: 05 Jun 2008 2:59 am Posts: 4731 Location: Arizona, USA Hi Everyone does anyone have the curves for the KT150 in triode mode. MarcVBelgium.

They do not "break a sweat" at that level. On the spectrum analyser’s screenshot you can see the oscillation’s frequency and harmonics. I prefer triode over ultralinear in my system/room/ears. So here are some more details, please have a look to the right table attached. . It needs to connect screen to plate via 100r or thereabouts resistor and not just open circuit the screen. S/N ratio at full power 98 dB. Note 1: Free shipping within EU. options : KT66, KT77, KT88, KT90, KT120, KT150 series. 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. • No 1. Member. EL34, KT88 or KT150 power output tubes. Feedback/Damping- up to 15 db. I have really tried my best to like Triode mode. 5″ deep x 8″ tall- weight (unboxed): 45 lbs. Owners stating something similar about the higher $ CJ amps specifically designed for KT150s. 5db full power; THD less than 0. The KT150 in pure beam tetrode mode is far from linear, like most other power tetrodes and power pentodes. 1, blue trace) was flat to 10kHz, with then rolloffs of –0. 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. Triode* or Pentode mode, Class-A*: Tube Complement: 8 x KT150: Load Impedance: 4 & 8 Ohms: Bandwidth: 8Hz-70kHz / -3dB: Output Power:Pentode mode: 2 x 125 W: Output Power:Triode mode: 2 x 80 W: Pure Triode mode has equal emphasis here.

This is with UL mode. Note: The supplied covers are too small for the (half pentode and half triode) or pure triode mode, using the excellent KT120 valves. You can choose the outputpower by paralleling. 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. Pure Triode mode has equal emphasis here. This is the latest version of the Ayon Triton with beautiful sounding KT150 tubes. 5″ wide x 14. Switchable between pentode and triode mode. It can run in Petode mode delivering 130W per channel or triode mode with 70W per channel pure Class A. I really like the sound in Ultralinear mode. 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. Oh, we did experiment with Triode versus Ultralinear mode again, but just as in JW’s system, here again, we all preferred Triode mode. The sonic characteristics of the KT150 are a little fluid and warmer when used in this way. Go to the KT150 data sheet plate curves in Triode Mode, and solve the curves for plate impedance, rp. 6 watts off Tubes Required 4 matched pair KT150 (Power output V1-4); 4 6H30 (Gain stage V5 and V6) 2 types of amplifier mode. 2 x 85 W. 97A±0. Vacuum Tubes This 30KG monster consists of 4 units Tung-sol KT150 power tubes by default, providing 55W (RMS) This Class AB amp that supports both ultralinear and triode mode doesn’t sound as powerful as MP-501, but it is more mellow, Same KT150 output tubes but single ended/half the watts. mode=65 watts Note: Ships with Tung Sol 6SN7 and Svetlana EL34. Here's the major part of capacitance when applied in Triode mode. 10 Hz – We have KT88 driver tubes, driving a pair of Single Ended KT150 tetrodes. 9dB) Input impedance: 100 Kohm; Recommended speakers: 4-8 ohm; Tube complement: 4x dual triodes, 4x KT120/KT150 Power Pentodes; Input sensitivity: 1. 9dB) • Input impedance: 100 Kohm • Recommended speakers: 4-8 ohm • Tube complement: 4x dual triodes, 4x KT120/KT150 Power Pentodes • Input sensitivity: 1. In Triode mode, you will get 30Watt for one pair, around 100Watt in ultralinear mode. Ideal also for more difficult loudspeaker loads. We are proud to introduce our new KT150 mono power amplifier, the Triton Evo. 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.

Instead of using 4 x EL34s in PPP, just a couple of KT150s can do the job. Bandwidth 8Hz-70kHz / -3dB. Posted by Triode_Kingdom (A) on December 20, 2024 at 08:23:57 . 6moons. The KT150 will be at Va~540v Can anyone comment on how close the Triode Strapped KT150's get you to the performance of a decent 300B SET. You can even get 150W for speech/modulator service (Class B triode). ) • Output power: 25 Watt per channel (KT150) • Frequency response: 20 Hz-25 KHz (-0. These are in fixed-bias mode which gives maximum power, cool running and even indicates valve condition. 8V triode mode / 1. in push pull, giving a hefty 150 watts per channel in ultra linear mode or switchable into triode mode to give a silky warm yet still powerful 80 watts per channel output. 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. 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. Search using Google: ". KT88, 6551, KT90, EL34, 6CA7, KT77, KT88, KT120, KT150. Frequency response at full power (limited by output transformer. 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.
