Slow wave structures in microwave tubes are rather large compared to the wavelength of the frequencies they operate at and so they can stand the heat. Tubes don’t suffer the same sort of problems. Yet the higher the frequency and power you need, the more heat… The technology is gaining ground, but it’s still pretty far off. Solid state has to be extremely tiny to work at microwave frequencies, and the smaller you make the devices, the harder it is to get the heat out of them. They are way more robust in space than solid-state, operate much more efficiently at microwave frequencies than solid-state and tend to fail gracefully or “die slowly” so you can get an idea of how long you can squeeze a little more life out if them, whereas transistors just fail hard. They just typically aren’t the tubes most of you are familiar with, but rather klystrons, TWTs, CFAs and so on – i.e. Tubes are used in space applications, a lot, actually.

Now it mostly consists of compressing the piss out of everything similar to what they do to commercials on TV to make them seem louder. Mastering is highly over rated in the post vinyl age, it was originally introduced into the recording process to take into account the fact that magnetic tape had a larger dynamic range than vinyl and prevented overmodulating the grooves so the needle wouldn’t fly out on the loud bits. The artist wanted people to scratch up the disc and released it in a folded piece of clear vinyl carpet runner for the sleeve! Needless to say it had no commercial potential, but it was interesting. I once did a recording which was released on flexidisc and we didn’t master it at all, just sent the tape off. A recording can incorporate elements that become the performance, such as taking advantage of MP3 artefacts (a dubious prospect) I have been involved in both and they are just different, neither one better or worse than the other. So in essence the non-noise distortion in tubes is described as a pleasant addition where non-noise distortion in transistor circuits is either cancelled out or very unpleasant.Ī recording can be a “record” of a performance, say a string quartet, in which case you want the final product to sound as much like 2 violins a viola and a cello as possible when played back. It’s the non-noise distortion in a tube that many use colorful terms to describe as a desired quality. In this way you can say that transistor circuits have a lower non-noise distortion than tubes. On the other hand, if you consider distortion alone without the noise component then transistors have the advantage that good design will use other transistors to compensate for the non-noise distortion. Good design can’t remove noise from transistor junctions. Noise in tubes comes from secondary emission and good design will minimize this. Transistors are exceptionally noisy when compared to tubes. Technically noise is a part of distortion because distortion is any component of the output that is NOT a component of the input. That is, if you include noise as a part of distortion.

Hmm, I am no fan of tubes but it’s true that tubes have lower distortion than transistors. Posted in Misc Hacks Tagged korg, tube, tubes, vacuum tube Post navigation

There will be further announcements this year, so don your speculation spectacles and head to the comments. There’s no word on what these tubes will be used in and there’s no data sheet. This new tube-chip thing was brought to life by Korg, makers of fine musical equipment and Noritake Co., manufacturers of vacuum fluorescent displays. Unlike the 12ax7, it consumes 2% of the power required of a normal tube, is 30% of the size of the normal tube, and lasts for 30,000 hours.

The Nutube 6P1, as this curious invention is called, is a full triode or half of a 12ax7 you’ll find in just about every tube amp ever. For 40 years, there really haven’t been many advances in tube technology. The tubes you’ll find in guitar amps and high-end stereos were first designed in the 30s and 40s, and when you get to really, really advanced tube technology you’d be looking at extremely small tubes made in the 70s for military applications.
