I understand that the bass is likely better with the 150's, but it seems a little boomy with my system. Jun 5, 2014 · Also possible the KT150 is designed to provide more power gain than the KT120, natch. The system will sound Jul 27, 2019 · Why the KT120 is better than the KT150 Posted by AbeCollins (A) on July 27, 2019 at 10:32:58 There's a discussion in another post further down about the Rogue Cronus Magnum integrated amp and the topic of KT120 vs KT150 power tubes came up. 5k load with 366V on the plate and 300 on G2, fixed bias, and I'm shooting for 22W. ), the TUNG-SOL KT120 Power Pentodes and the more recent TUNG-SOL KT15.

Mar 24, 2021 · Agree Ken, go for it, I have an arc amp as well with kt150, and it is driving revel salon 2, 86db speakers and the sound is awesome. 65mA was the max I would set it, and has run without issue for a few years now. Dec 13, 2016 · The KT120 and KT150 are both pentode devices and the KT88 and KT100 are described as beam tetrodes so no, I wouldn't think these can be easily interchanged even though the data sheets have the same "pin-out". Interesting to see that basically there is no significant difference between the KT120 and KT150. (The tubes have similar characteristics except for plate dissipation. I wrote about the VS115 and the sound of the KT-120 tube on this forum several years Jul 21, 2024 · TS 6550 vs TS KT120 tubes.

Jul 22, 2024 · Title says: New Tung Sol 6550 vs KT120 vs KT150 Sonic Comparison Post #7: Various contributors to these forums often sideline the little stumpy 5881; on an open chassis it may look a bit odd to other tube lineup´s but my early Tungsol versions beat the 6L6 and are capable of near 6550 power throughput. Apart from a fairly marginal difference in terms of Cathode Filament Current and a Plate Dissipation of about ten Watts in favour of the KT150, from an electrical point of view (Anode Voltage, Impedance, Transconductance etc. ) 2. Jul 21, 2024 · Checking the tubes, the interlectrode capacitances are closer between a KT88 and KT150 than the KT120, but not that much. - Due to the higher limit of Ik (275mA versus 250mA) for the KT150 2 more configs with higher output power are possible. The answer isn't so straight forward and thus I Jul 21, 2024 · I had the same problem with one amp which had 6550 tubes, switch to KT120, but the PS was complaining at the "normal" KT120 bias level 70%. I'd be interested in comments on the sonic differences to expect with KT-88's. I was so sceptical about a 150 watt tube amp being able to drive these, but trusted my dealer. If I change the circuit design or parts, say to sound brighter, we are again simply comparing the two TS tubes for sonic differences, as the amp/system cancels out of the equation, just like in point 1. Feb 28, 2017 · KT120's can be used in place of KT88's in many amps, as long as the power supply, and bias system can accomodate them, the heater current with the KT120's is a little higher ie; around 150, to 200ma more than a regular KT88, However, the surge current is greater, especialy with the KT150's, [in excess of 3 amp initialy] But both the KT120's and KT150's settle down after a couple of seconds The KT120 is a beam pentode, that, until the KT150 was the most powerful audio tube you could buy. The KT150 is an octal beam tetrode, and the egg-shaped glass helps dissipate heat and reduces microphonics. I have only tried it with the 150's. My first experience listening to the KT-120 tube was with the ARC VS115 I bought that ended up claiming my right bicep tendon. The shown difference might even come from the variation in production. Going to a KT150 is dangerous for an amp not designed for it as the heater current is much higher (2A Vs 1.
