Parallel single ended vs push pull So, in this article I'll attempt to bring out the virtues and drawbacks of both single ended and push pull op-eration, lay them out side-by-side, and try to avoid rais-ing the ire of both Camp Push Pull and Camp Single Ended along the way. Apr 6, 2021 · For an amplifier with no negative feedback, and Class A operation, one difference is . The transistor on the rigth must dissipate the same power of the tube (about 45watt) so is necessary to use a heatsink with high aspect Oct 4, 2020 · Push pull amps can operate class A, class B, or anywhere in-between. The push pull will give you substantially better verifiable performance all around. Class AB and B are more efficient, so the tube can safely tolerate a higher HT and lower load impedance than in class A, which means more power. Why does a Push/Pull amp (with two tubes) put out more wattage than a class "A" single-ended with the same two tubes wired parallel? Re: Push/Pull vs two tubes parallel (Single Ended) by 54Goldtop » Sun Dec 07, 2014 8:24 am I would agree that those participating are being cordial and contributing allot of opinions that overlap to some degree - I wouldn't go as far as to say you all agree, or a general consensus is being formed. With a single ended stage you are wasting most of the useful potential of the KT88. Ot classictone 40-18031 (15W) PT classictone 40-18027 (100ma) Between a single ended 6v6 and a parallel single ended 6v6 power section I notice little to no volume difference Re: Push/Pull vs two tubes parallel (Single Ended) by 54Goldtop » Sun Dec 07, 2014 8:24 am I would agree that those participating are being cordial and contributing allot of opinions that overlap to some degree - I wouldn't go as far as to say you all agree, or a general consensus is being formed. is similar to a totem-pole arrangement for transistors in that two devices are in series between the power supply rails, but the input drive goes only to one of the devices, the bottom one of May 7, 2021 · Push pull triode, pentode, or Ultralinear. It produces from 40 watts of Triode-strapped sound to 120 watts of ultra-linear power Which would have more volume? (Loudness/power) Single ended 6l6 Parallel Single Ended 6v6 According to what I know and have read it looks like the 6l6 will be about 12w if biased right and the PSE 6v6s are close to 9w. .

By varying the load you can get any current swing and power absorbed that you want for a given voltage swing. Class B? It would seem that in both Jun 6, 2003 · In its simplest form, this type of circuit is known as "single-ended". Is there any difference in the way the circuit performs when it is operating in Class A vs. Feb 11, 2004 · Hi, For about the same output power, do parallel single ended sound better than push-pull? One is easier to build (tube matching or something else) Nov 4, 2020 · These speakers are also likely designed to work best with a bit more damping from the amplifier, so a traditional push-pull amp with relatively low output impedance seems like the smart decision. Dec 30, 2013 · For a push-pull amplifier, the pull-up transistor is on for 0 degrees through 180 degrees, and the pull-down transistor is on for 180 degrees through 360 degrees. In contrast, each device in the push pull circuit conducts during exactly 50% of the signal cycle. Dec 2, 2021 · The only time I've built a parallel SE amplifier is for guitar use and I did it specifically because I wanted the single-ended distortion characteristics (it's a very bright-sounding amp for lead use). Jul 25, 2018 · You can group them into two basic divisions: push-pull and single-ended; with numerous variations within each group, such as ultra-linear connection, parallel feed, and so on, and you can use different devices (triodes, pentodes, and so on). Seemed to work just fine with the tubes biasing up different. May 3, 2017 · Single ended amplifiers require a more expensive gapped output transformer to withstand unbalanced DC, better power supply filtering and design, more expensive tubes, and larger and more esoteric speakers. Why does a Push/Pull amp (with two tubes) put out more wattage than a class "A" single-ended with the same two tubes wired parallel? Re: Push/Pull vs two tubes parallel (Single Ended) by 54Goldtop » Mon Dec 08, 2014 7:15 pm PDF - Are you suggesting that the wattage spread between push-pull and single-ended is not as vast as commonly believed (see below) Last edited by 54Goldtop on Mon Dec 08, 2014 7:23 pm, edited 1 time in total. We have a Single Ended amplifier using a push-pull transformer and the current mirror balance the bias current on the transformer. If we consider purely sinusoidal signals, it is clear that the output device in the single-ended circuit conducts current during 100% of the audio signal cycle. com/products/supersonic-v1-op-ampFor stunning revolutionary 3-way speakers visit - https In my push pull cathode bias amp I did try using a 6v6 in one socket and a 5881 in the other. May 12, 2023 · Re: Push/Pull vs two tubes parallel (Single Ended) by 54Goldtop » Mon Dec 08, 2014 7:15 pm PDF - Are you suggesting that the wattage spread between push-pull and single-ended is not as vast as commonly believed (see below) Last edited by 54Goldtop on Mon Dec 08, 2014 7:23 pm, edited 1 time in total. See full list on circuitsgallery. Why does a Push/Pull amp (with two tubes) put out more wattage than a class "A" single-ended with the same two tubes wired parallel? First idea - Single Ended with Current Mirror This is the first circuit idea. A push pull triode amp has a symmetrical damping factor. Feb 28, 2023 · Single-Ended Versus Push-Pull Dec 4, 2014 · Re: Push/Pull vs two tubes parallel (Single Ended) by pdf64 » Thu Dec 04, 2014 8:47 am In both cases, you might be looking at the same current and power dissipated in the tubes themselves, but the voltage on the push/pull will be, by nature of being push pull, roughly twice that matt, I hope your headache has cleared up? A Single Ended Push–Pull (SEPP, SRPP or mu-follower[10]) output stage, originally called the Series-Balanced amplifier (US patent 2,310,342, Feb 1943). One tube "pushes" to amplify the original signal (+) and the other tube "pulls" simultaneously with a reverse phase "mirror" image of the signal (-). Class A is still class A, it doesn't matter whether it's push pull or parallel single ended, so for a class A push pull amp you need a 10w OT. There are devoted followers of all types who believe theirs is the best, often with great conviction! May 3, 2017 · Single Ended Vs.

Thanks Push-Pull Versus Single-Ended Amplification Push-pull amplifiers have two power tubes (or transistors) that work with mirror images of the input signal. Dec 2, 2014 · Because push-pull amplifiers can operate in class A, class AB, or class B. A perfect class B amp can make roughly 3x as much power as the class A version, so a 30w transformer would be the upper limit. . com The two main types of output stages for guitar amp use are single-ended and push-pull. Derived from the Transcend Push Pull stereo amplifier, it is able to utilize EL34, KT88, KT120, and KT150 tubes. Just for the fun of it. Re: Push/Pull vs two tubes parallel (Single Ended) martin manningFri Dec 05, 2014 6:26 pm Current swing. A parallel triode single ended amp has a non-symmetrical damping factor. Single ended amplifiers are stuck with class A. They'll make 100 watts a pair in push pull, Single ended, good luck hitting 25. It was odd to look at though. These terms refer to the amplifier output stage circuit "topology", which is the way in which the components in the output stage are connected. These parallel push-pull mono blocks are different than any amplifier on the market, as they use two independent push-pull amplifiers in each chassis and sum the signals at the output transformers.
