Free tube amplifier design software

Yes, there are circuit simulation tools out there that have component models for tubes. You can load up input waveform data and capture the output. Extremely useful to validate you have correctly functioning circuit bias, gain, frequency domain performance etc Messages There are free versions for download, do a Google search.

Silent Sound Member. Messages 5, You can't really design a good tube amp in software. It has to be done on a breadboard with trial and error. If you need help with some of the basic circuit parts, like just to make sure they'll work, then I would probably start off with SPICE.

I downloaded it and gave it a whirl. But ultimately, I found it wasn't worth my time. Tube amps are fairly simple circuits, so unless you're doing something like a digital modeler, I think your time would be better spend learning how to design various stages of an amp versus learning how to use a software program.

There are also some other smaller programs just for specific parts of the amp. You may check out his page for those, or perhaps Google to see if there are any others out there. Most notably, here, you will learn the concepts of operating conditions, loadlines, biasing techniques, and amplifier classes. Continuing, the guide discusses how to design an integrated push-pull vacuum tube amplifier.

To do so, it starts from the single-ended configuration, then it introduces the push-pull configuration. Consequently, the various needed stages power, phase-split, and input stages , and global negative feedback are discussed in details.

A significant part of the guide is also dedicated to the power supply unit design for a vacuum tube amplifier. First, it introduces the rectifier configurations and filters to reduce voltage ripple, and to have a quiet amplifier.

Then, it explains how to estimate the expected output DC voltage, ripple, and the current delivered. Furthermore, it also discusses how to design the power supplies for the fixed bias circuit and for the filaments of the vacuum tubes. After launching this amplifier software and opening an audio file to amplify it, you need to click on Process menu and select Volume option from there. Also, it provides you option named Custom to specify the desired value for gain.

Clicking on OK button applies new gain to the audio file and you can play it to check out its quality. Expstudio Audio Editor is next in this best free audio amplifier software list. It comes with some built-in presets for audio amplification. Also, you can perform manual audio amplification by adjusting the slider given on its interface. All of these audio amplification options are present under Effects menu.

Prior to applying amplification on audio files, you can click on Preview option to listen to a sample of the audio with amplification. After getting a satisfactory result, you can save the audio file as WAV file. Using this option, you can save amplified audio in below-mentioned formats with the adjustable sampling frequency, bit rate, etc.

It provides many other options to alter audio files as per your need. WaveShop is an open source audio amplifier software for Windows. When you perform audio amplification, it performs audio waveform clipping as well. Thus, the amplified audio file may compromise on quality. After accepting subsequent options, you can amplify audio at the desired level. It also lets you apply many other effects to audio files, like: Fade, Normalize, Resample, Reverse, Invert Silence , etc. Naturpic Audio Editor is a good audio amplifier software for Windows.

These presets are either in db, or in percentage. This might help explain why the old Triad tube power transformer model R8-A works so well. It holds three secondaries: 5Vac 2A, 6.

I placed the 5Vac and the 6. It works. This project just uses a two-lead zip cord to attach to the wall socket. I planned on replacing the power cord later, when I can find the fancy shielded three-wire power cable I own. But then, I might not.

Unfortunately, my house ground and the wall neutral see about mV of AC between them should be 0Vac , which explains why I sometimes get hum when I connect the house ground to the chassis in some equipment. I have changed the series resistor at the top, since the last time I posted the schematic. If the Bud box were just one inch deeper, I would have no reservations recomending this project to other audiophiles.

The box was only 13in wide by 7in deep by 2in tall. A better choice would be 10 inches deep and 2. Well, how does it sound? After the fight I put up to get the this project done, I was predisposed to not like the sonic results.

My HDs gladly receive the output from the headphone jack, which prompts a wonderfully natural presentation. I even tried my Grado SR headphones and the results were surprisingly good; true, the bass was a tad thin, but the mids and highs were fine. Considering that the Grado headphones are almost one tenth the impedance of the HD headphones, this is a miracle. The results were also much better than I expected.

The line outs also sound much better than I expected. As the first notes of music poured forth, I was impressed.
