Consonance Cyber100 15-Year Anniversary KT88/KT120/KT150 integrated Tube Amplifier Although the KT88 aren't triodes but, if properly applied as such in a circuit with 35 push-pull watt output, they can exhibit surprisingly good linearity, steady performance and approaching that of the real thing - something you'd expect from triode units. It is a comprehensive amplifier that not only can play very sweet and smooth female vocal, but also can handle high dynamic range symphony unbelievably well. There are practical implications beyond the obvious sonic differences: a KT150 amp is going to be PP design, putting out more Wpc and many (most) will allow the use of 4 ohm speakers. This is a very, very nice amp. It is important that you ONLY purchase KT150's from Upscale Audio. 01% or less distortion, while the transistor is. The new Spirit-III is not a simple update; it is a re-design featuring new operating and protection circuit boards. We wind our push-pull output transformers on two chamber bobbins which ensures full capacity and resistance balance. I think Alex Gendrano's KT88 SE schematic could be modified to suit the KT120 or KT150. for audio serice applications oxide coated indirectly heated. It has a big power supply, big output transformers, and designed for the excellent new Tung-sol KT150/120. Of course it all depends on the amp and the plate voltage. There are types of timE Amp, marzE Amp, and pEar Amps of different designs too. The grid stopper resistor RGS blocks radio frequencies while allowing audio signals to pass. A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. Also, use the search box on the top right. I prefer the KT120. Your shopping cart is empty! Show All Categories. LW6-180 SCHEMATIC Figure 3is the LW6-180 schematic, and Table 2is the parts list.

The tube amp has been modified from the builder to have the correct input sensitivity, and the mono amps have a variable gain. With other brands, this may be when you have to break out the soldering iron to replace a plate resistor, and replace two or four tubes because your amp requires matched sets. The valve positions are marked on their packaging and the circuit board, so it’s hard to go wrong. The very good result got with the PP2010 and availability of a pair of old 10Kohm Tecnotrafo (Italy) push-pull transformers have forward me to create this new amplifier. for audio serice applications oxide coated indirectly heated. KT88 is upwards compatible with 6550 tubes. Techmoan Recommended for you. Physically it's almost practically indistinguishable from the model it replaced, being quite a large device at 356x203x406mm and weighing in at 15. While a tubed amplifier may measure a sleazy-looking 0. Sterling MK1 Printed circuit board EL34 stereo or 5 channel with integrated passive pre-amplifier stereo power amplifier 2. Still most folks do not really need more than 40 to 45 watts of audio power. For me a rather idle question: I remain synonymous in the future all circuit concepts open up - digital amplifiers perhaps excepted, because before the A / D conversion of fine analog signals from record player and tape recorder still frightening back, Epsilon and KT150 fan. price are special Their class A/B analog amps Inputs: 3. With PrimaLuna, you just replace the tube it tells you to (no matched tubes required), and turn the amp back on. And it comes with many features! An integrated version of our MB90 MKIIs. It took years of development and refinement resulting in unique minimalist true balanced circuit topology to produce an accurate and seductive holographic soundstage. The REF160M also features a proprietary auto-bias circuit that works with various tubes types, including 6550, KT88, and KT120, in addition to the supplied KT150 and works constantly to maintain precise bias of the output tubes, while also adjusting for tube wear.

My knowledge of electronics theory is limited (relating to valve tech) but I'm confident with a soldering iron, as well as following basic safety guidelines. It has a big power supply, big output transformers, and a big sound. The valve positions are marked on their packaging and the circuit board, so it's hard to go wrong. Fujita SPECIFICATIONS (Pre-production) VACUUM TUBE Stock tube set: 4 X EL34(6Ca7), 4 X 5965A (or 12AT7) You can also use :6L6GC,KT88, KT120 or KT150. which is good. GABRI'S AMP CALYPSO KT-150 Sound quality and power in "Class A". It is my feeling. With PrimaLuna, you just replace the tube it tells you to (no matched tubes required), and turn the amp back on. Modded TPA3118 Class D amplifier/Modded TPA 3255 power amplifier/Anaview AMS1000 power amplifier/KT88 SE FAST with a 6. 01% or less distortion, while the transistor is. The CTA408’s power amp section is built around a quartet of KT150 output valves used in an under-stressed circuit with a claimed power output of 75W per channel. This is a Power Amplifier too (there is a group pre-amp input). For some circuit designs this is a problem, for some its not critical. Zero feedback, neither local nor global. This is actually the same circuit you will find in the Marshall 2550 and 2555 Silver Jubilee amps labeled as high and low power. Vacuum Tube Calculators Basic Theory - using 21st-Century technology to design vacuum tube preamps, power amps, and power supplies System Design - a professional methodology for crafting a complete guitar amplifier. Read the review by Hi Fi World. I think that it is a very good amplifier for the simple circuit as long as EL 156 - China and EL 34 are used. It can work with various types of penthodes: KT120, KT90, KT88, 6550, 6CA7 or EL34. Just got my KT150 tubes for my ARC REF75 and it was a plug and play install. the world’s finest vacuum tube amplifiers. Tung Sol KT150 power pentode tube Made in Russia With a massive plate dissipation of 70 watts, the Tung-Sol KT150 is the most powerful octal beam tetrode ever produced A pair of KT150s can allow an amplifier with a power output approaching 300 watts to be built. Tung-Sol KT150 The overall sound of the KT150 is thunderously powerful.
