    What are the advantages/disadvantages of different amp topologies?

    It's not about the capacity. If you just put your hand to the RIAA input tubes of the open design preamp, you will hear a hum. The reaction of unshielded input cables in these devices is similar.

    What are the advantages/disadvantages of different amp topologies?

    Try a cable with twisted wires on the MM input of the preamp, then you will see the same effect or a different one.

    What are the advantages/disadvantages of different amp topologies?

    I believe that the shielded wire kills the sound. An exclusive place for its use is the phono cable. I don't use it in amps, not even phono preamps. At the same time, there is not the slightest hum.

    What are the advantages/disadvantages of different amp topologies?

    If you added that this is your opinion and not the truth, then it would be correct. Very reminiscent of the legend of the Procrustean bed.

    What are the advantages/disadvantages of different amp topologies?

    I will tell you my truth about output transformers, maybe it will be useful to you. I make output transformers in my amplifiers with a lower operating frequency of at least 7-8 Hz at the level of - 3 dB at half the maximum output power. Such a transformer provides a much more natural sound than...

    What are the advantages/disadvantages of different amp topologies?

    What size and design do you consider the output transformer to be good? Do you pay attention to the technical characteristics of these devices?

    What are the advantages/disadvantages of different amp topologies?

    The speed of propagation of the signal in the amplifier is not instantaneous, so the feedback from the output to the input, for example, to the cathode of the input tube, is the correction of the signal that arrived at this moment with a signal from the past that has already reached the input to...

    Connecting one end of the secondary winding of the output transformer to ground is necessary for safety, especially in amplifiers with high anode voltage, as in tubes 211, 845, ??70, especially 833?. This does not increase distortion, but reduces the maximum operating frequency. For example, in...

    The requirements for the anode choke are at the level of the requirements for the output transformer for the CE amp. Add a quality capacitor with a large capacity and an output transformer that is a bit simpler than usual due to the lack of clearance. This has nothing to do with hum, but it...

    I think that Atmasphere does not have common sense, but the desire to be the last to speak. Even when it's a set of words, which is almost all posts.

    He has repeatedly shown ignorance of simple things before, so don't be surprised. I sent him many times to read textbooks. It is he who runs the advertising company of his products.

    Can you back up your words with facts? Where are the links? It's very strange that everyone at Atmasphere is wrong, but instead of evidence, he ignores the question.

    I know the opposite, and I ask where did you read such nonsense? I already wrote about my experience above, and later it was confirmed by another study: PP amps, and OTL is a PP amp, 1/3 of listeners like it. I think that you are trying to convert someone from the rest of the listeners to your...

    I make amplifiers that I like. And I don't regularly tell anyone that they are better than others. But I think it's true.

    You firmly believe that things that are bad for you should be better for others. It is very self-assured, but has no foundation.

    There is no electrical DC feedback in your circuit diagram, but there is an option to do the feedback function manually. And this function is performed by the user. Huge milliammeters on the front of the devices prove the importance of these manipulations. Maybe in the latest models you are...

    I can see everything well. You wrote about the lack of feedback, but there is. It does not affect DC modes, you are right. But you entrusted the user with the function of constantly monitoring the milliammeter and adjusting its zero. I would never do that. The user only has to turn on the...

    There are no capacitors, but there are feedbacks. Can you tell me what role the 2M resistors play? As we say, "there are no friends for taste and color." You have feedback in the amplifiers. Ask someone to explain your schematic diagram to you. You show a circuit diagram with feedback and for...

    Output resistance and speaker impedance are completely different things. But they are interconnected in tube amplifiers. Read the tutorial, don't be shy.

    I have one tube 6C33C gives a power of 20 W, you have two tubes. Q: Where is the best performance? I don't care much about your words about the possibility of giving a giant current of your tubes. I read manufacturers' datasheets and draw conclusions. I believe them, not you, because I also...

    I did not write that with the same tubes and components, I repent. Yes, you are right, there are other OTL. OTL is a combination of tubes, active elements that work with weak currents and a speaker that requires a large current. The combination, in my opinion, is unnatural. Tubes are used in...

    You haven't heard a good SET amplifier. Any PP amplifier is nervously smoked in a corner compared to it. PP amplifiers have the problem of the first Watt and larger odd harmonics, these are their main disadvantages that make their listening not very comfortable. But there are connoisseurs of...

    There will never be objectivity in this matter. I have witnessed many times how one audition was evaluated by different people with a diametrical difference.

    What I am saying is that the assessment may not be entirely accurate. The general image is well received, but the details, which are much debated here, raise questions.
