Push–pull output
LOG IN. First post here and appreciate any replies. While not new to high end audio, I've never had a tube amp. Thinking about a tube amp as I've never had one and have read a lot about them, mostly all positive. Never having heard a tube amp, I'm wondering if I'd be able to hear a difference between the push-pull type and the single ended type.
Not a huge budget as I'm on a fixed budget. Appears I could get more watts per dollar with a push-pull amp but don't need a whole lot of watts as this is for the top end of my system.
Also like to get a new SS amp for my bottom end but that's another subject. Would I be able to hear a difference between the two types of amps? Thanks for the input. BTW, not really anywhere I can audition the two types.
Edit Delete. Should add that the efficiency of my top end is 94db tweeter and 95 for the midrange. I'm going to add, there can be a pretty good amount of weight with most well made valve amps.. The exception is a Crimson Carver. It's still pretty hefty. I think.. You said disabled! Weight and issue? You can't beat that. I think they are under 3k. They are a great sounding unit. It will do the bass and you can add a good class d for the bass later. Best of both worlds.
Carver run cool too. Touch a valve no problem.. I repaired it. The kids knocked the valves out while it was on.. BOOM Just replaced the valves it was fine.. Snapped off though.. I was pretty impressed..
A lot of amps that would have been a pretty heafy bill. Just a set of power valves.. There is not a lot of Carver talk.. They are good units for the money and easy to take care of..
Bob Carvers way It is hard to offer any meaningful generalizations about the differences between pushpull and single-ended triode SET amps; there are many good and bad examples of both types. I am personally a fan of lower-powered tube amps and I own both SET and pushpull tube amps.
While SET amps are very simple and minimalist in design, this does NOT mean they can be made at lower cost than a roughly comparable pushpull amp because they demand specialized output transformers that tend to be expensive. Because a SET output transformer must be conducting at full power through the primary windings at all time, the transformer must be pretty large even when the output is modest.
I have not heard low-priced examples of SET amps that perform satisfactorily. Most of the better sounding triode tubes deliver quite low power when used in SET amps e.
There are more powerful triode tubes, such as the , that can be used in SET amps, but, the much higher voltages involved make them considerably more expensive if they are to be made to operate safely and reliably.
I think both SET and pushpull amps can be made to sound very good. Recognizing that this is a rough generalization, I tend to find pushpull amps to be more "punchy" tighter, more powerful bass , but, that more punchy quality makes the sound just a touch more "mechanical" sounding and less natural and relaxed than the sound of SET amps. That is NOT to say that either kind of amp is lacking in dynamics, that is certainly not the case.
At more modest listening levels, I find tube amps to be considerably MORE dynamic, lively, and engaging than solid state amps. Of the two favorite amps that I own both with output in the watt range , I slightly prefer my pushpull amp custom-made rebuild of a Western Electric amp over my parallel SET Audio Note Kageki twin 2a3 tubes per channel. There is another kind of tube amp you should also consider.
This is an output transformerless tube amp. These types of amps are capable of delivering astonishingly dynamic and vibrant sound, again, even when overall volume level is modest. Like any other amp type, the specific design and voicing matters, so one does have to make personal choices on the specific model.
A push-pull amp is an easier transition from a SS amp. Set amps are a different animal. Thanks for all the input. Lots to think about. Thumbs up. Nice idea, I agree, go Push Pull. Your efficient speakers means you can easily stay in the wpc power range. That gives you lots of options, lots of competition there. Having return options is a great means to success. Some new tube amps, like my Cayin offer two modes of operation: i. Not needed, just mentioning it. I and all my friends prefer the more common ultra-linear mode.
Many tube amps offer easy external Bias control, with external adjusters and meters, I wish my amp had that. An OTL amp was mentioned. The entry level S would be the amp for you. All Atma amps are equally good. The only difference is power and price.
Super reliable and easy to use. M60s would offer more flexibility if you ever changed speakers, but at a higher price. Sonic character is similar if you happen upon M60 reviews, and are wondering if those comments would apply. Cheers, Spencer. If not the efficiency of your speakers will be a problem with most SETs. Regular old home made x-over on the mid to tweeter. I think there is a lot of helpful advice in this tiny thread.
The Carver is a pretty good amp at very decent price. White the advice on a solid state alternative First Watt F2 may not slake your curiosity over tube alternatives, it probably would deliver quite nice sound I've heard the First Watt J2 and SIT amps and they are very good; I have not heard the F2. As I've stated before, I like OTL amps and the Atmasphere amps mentioned are very stable and reliable versions of such amps.
You could look into vintage gear, but that takes a bit of help from knowledgeable friends or a good dealer for a novice to get into that game. Old gear has to be inspected and perhaps repaired or reconditioned. Once that is done such gear can be reliable for a very long time. For newer gear, it would be helpful to know what is the price range you are shopping.
Also, if you are handy, you could save some money and get really good gear by building a kit. I heard the Elekit tu single-ended b amp, and it is terrific and the instructions look pretty straightforward and even a novice should be able to tackle that build. I noticed that Elekit also makes a single-ended amp kit utilizing the 6L6 tetrode tube a personal favorite in type of tube that looks interesting I have not heard it.

Single ended push pull transistor amplifier
Push-Pull amplifiers offer some advantages with respect to the single ended ones. Push-Pull transformers core can be made smaller than single ended ones and without air gaps. In fact, the current from the centre tap flows in opposite directions through the two half of the transformer and one current cancel the electro-magnetic effect of the other. Two additional advantages are the reduction of the harmonic distortions, and the increased output power, as discussed below. For instance, in Figure 21, grid voltage lines intersect the loadline more densely with an anode voltage higher than V, than with an anode voltage lower than V. Therefore, half signal is amplified very differently than the other half signal. Remember that the input signal corresponds to different grid voltages, that is different points, identified by the intersection of the grid voltage lines with the loadline. Figure 22 shows the effect of this nonlinearity. The upper plot shows the anode current of two vacuum tubes in push-pull. Since each vacuum tube amplifies a phase inverted signal, with respect to the other, the currents at the anodes of the two vacuum tubes are phase inverted as well.

It seems to be an example of some natural law of cussedness that review articles are rapidly followed by a spate of further publications on the subject; and the article on ' Output Transformerless Amplifiers ' February, , issue, p. As some of this further work has followed what were only sidelines of the original article, further information is given here, together with notes on other developments. The Philips single input series-connected output stage shown above, based on Fig. The signal input for the upper valve already contains second-harmonic distortion produced by the lower. This will give second harmonic in the upper valve by amplification , and this will be out of phase with the second harmonic produced by distortion in the upper valve. The signal input for the upper valve is out of phase with that for the lower as it is produced by amplification in the lower valve.

Single-Ended Class A amplifiers have certainly hit it big in the four years since we began testing the first Aleph 0. So is this just another audio fad, or is there something fundamental about this kind of design, justifying a revival of the old approaches to amplification? When I started designing amplifiers twenty-five years ago, solid state amplifiers had just achieved a firm grasp on the market.

RELATED VIDEO: Push pull amplifiers: what's the difference from Single ended?A push pull amplifier is an amplifier which has an output stage that can drive a current in either direction through through the load. The output stage of a typical push pull amplifier consists of of two identical BJTs or MOSFETs one sourcing current through the load while the other one sinking the current from the load. Push pull amplifiers are superior over single ended amplifiers using a single transistor at the output for driving the load in terms of distortion and performance. A single ended amplifier, how well it may be designed will surely introduce some distortion due to the non linearity of its dynamic transfer characteristics. Push pull amplifiers are commonly used in situations where low distortion, high efficiency and high output power are required. Generally this splitting is done using an input coupling transformer.
There is disclosed an amplifier circuit of the type using differential amplifiers at the preceding stage of the output stage of an SEPP Single Ended Push Pull circuit. This amplifier circuit is of a structure such that a power supply voltage is delivered from a second power supply circuit independent of a first power supply circuit for transistors constituting the SEPP circuit to the respective differential amplifiers.
