But in a PP amp with CFB, then they will be excellent just like the others because of the way the local NFB is used. This is not only the decision 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. Of course, now I am thinking about SED Winged C 6550Cs and what they would sound like in Triode mode. ) - speaker driver "Re" is at 5. Input sensitivity at full power 750mV. It uses the new, powerful and musical KT150 power tube, with requisite changes to transformers and several minor circuit elements. Frequency . 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. • KT150, KT120 versions available • 6550, KT88, KT120, KT150 compatible • Dual toroidal power transformers • Input sensitivity: 1. The choice of signal and power tubes have a significant influence on the sound and hence on the inspiration and joy of listening. In Triode mode, you will get 30Watt for one pair, around 100Watt in ultralinear mode. Vacuum Tubes The choice of signal and power tubes have a significant influence on the sound and hence on the inspiration and joy of Switchable between pentode and triode mode Ideal or more difficult loudspeaker loads. The sound of the I was totally a triode-mode guy for the first 18 or so months of the 150s. ) So I put the Brimar back in for the gain tubes (the 2 in the middle) and the Mullard in the other 4 positions. . L. But in a PP amp with CFB, then they will be excellent just like the others because of the way 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, 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 can use EL34s, KT88s, KT120s, and KT150s All else being equal, triode mode needs different feedback and different output transformers. They are rather easy go drive and pentode or cascode input and a driver stage will have enough gain. The KT150 will be at Va~540v Hi Everyone does anyone have the curves for the KT150 in triode mode. 5V Ultra Linear mode • Inputs: 1x line unbalanced stereo (RCA and XLR connectors) Switchable between pentode and triode mode Ideal also for more difficult loudspeaker loads. subckt kt150" or other model. I look at the triode curves for KT120 and KT150 and I see the op point at around Ia=100mA, Va=400-450V, Pa=40-45W and Vg=-50 ish volts to yield around 8W with a 5K The KT150 in pure beam tetrode mode is far from linear, like most other power tetrodes and power pentodes. 6. The OPT is 4. This amplifier is an exception to the typical “push-pull” signature sound and does not sound strident or bright in any way; it has warmth, dynamics, and excellent spatial qualities! KT150- triode-mode= 45 watts/U. Input Impedance at 1 kHz 47KΩ. Then Go to the KT150 data sheet plate curves in Ultra Linear Mode (at the UL tap % of your output transformer), and solve the curves for plate impedance, rp. 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 The new KT150 is a nice huge thing, but a classic one is KT88 or 6550. Load Impedance 4 & 8 Ohms. 8V triode mode / 1. This is not only the decision between good and bad tubes but finally • 6550, KT88, KT120, KT150 compatible • Dual toroidal power transformers • Easy Manual Bias Adjustment on the back plate • Triode / Ultra Linear selector switch • Handcrafted custom audio grade transformers.

The amps were going way upscale; the speakers were Sonus Faber Amati Futuras ($36k / pr). Ideal also for more difficult loudspeaker loads . Joined 2016. Read the latest review by Hi Fi News. Bandwidth 6Hz – 70kHz / – 3dB. Straight out the gate i will say it sounded better than the Willsenton 300b, but only with the KT150 tubes in it. Does it succeed? The user manual suggests that most listeners Switchable between pentode and triode mode. Vacuum Tubes. Input sensitivity 900mV. Good for the 92+ dB efficiency crowd. There probably are more “triode mode” than ”pentode mode” Spice models floating around for the big boys - hence the question. The KT150 will be at Va~540v Ia=120mA, Vg=-60. My reference system CJ amps are set up in ultra-linear with 6550 tubes, although the CJ Premier amp can be factory or service tech adjusted to run in triode mode using EL34 tubes. (I think KT150 in triode is 54 watts/channel. Choose from two elegant glass blasting anodizing finish choices to suit your aesthetic. 5V Ultra Linear mode • Inputs: 1x line unbalanced stereo (RCA and XLR connectors) • Available Colors: Matt The Primaluna reps demoing the Dialogues preferred triode mode and the KT150's, they said it's the best the amps can sound. 8 Ohm (yeah, lot. Large Image: KT150 Tung-Sol specifications (PDF) Switchable between pentode and triode mode. Now it has more detail but is still super smooth. 5V Ultra Linear mode • Inputs: 1x line unbalanced stereo (RCA and XLR connectors) • Available Colors: Matt Black, Frozen Silver Full-featured true balanced tube stereo power amplifier Switchable between pentode and triode mode 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. This is not only the decision between good and bad tubes but finally 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 fact that the glass envelope has no flat sides means the Tung-Sol KT150 has no problems with microphonics. You can choose the outputpower by paralleling.

Full-featured true balanced vacuum tube mono power amplifier Switchable between pentode and triode mode Ideal also for more difficult loudspeaker loads. As you said, each tube sees 3000 Ohm load (parallel operation on 1500 Ohm primary) - triode mode (distortion characteristics vs pentode mode) ? - ~200W into nom. The A-2000 25th Anniversary is an updated version of the original A-2000. Only one way to find out for myself I guess is buy a quad and try em. 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). This is not only the decision between good and bad tubes but finally the kt150 is a beam pentode power amplifier primarily designed for audio service. EL34, KT88 or KT150 power output tubes. Output Power / Triode mode 1 x 100W. mode When I added the extra power of the KT150 I found I prefer triode mode. 2k ohm which is suitable for KT150 and also 300B, allow subsequent modification (320v tap is therefore prepared for 300b or other lower power tube). IIRC there is a little more power available with the 150's, making triode mode more compatible with more speakers. Go to the KT150 data sheet plate curves in Triode Mode, and solve the curves for plate impedance, rp. Tube Complement KT150. Effectively giving you two amplifiers in one! 100 watts of valve power is easily comparable with Switch between Triode and Ultra Linear mode with a simple flick to find your personal sound nirvana.
