Bead Rolling System For S.S. Tube Mill


The results of tube-rolling are dependent on your audio components, the room, and your ears. Tubes are a personal choice, so anything in this guide is just that, a guide. There are no definitive recommendations, and beware anyone who gives you any. First, a few basics:. PrimaLuna products, for example, come stock with a wonderful tube selection.

The amps and preamps are voiced using those tubes and there is absolutely no need to change them. Tube rolling is about experimentation and fine-tuning. Issues such as bloated or absent bass, or excessive harshness are usually traced back to speaker placement, room issues, or component mismatches. They cannot and should not be fixed by changing tubes. A tube in one circuit can sound different from a tube in another.

The best source for information on how a tube would work in your component is the manufacturer of that component. Tell your manufacturer to create a cool guide like the PrimaLuna Tube-Rolling page.

If tube-rolling is a chore or cause for anxiety and rudeness! This bears repeating. This guide points you in the general direction, it does not--and cannot-- promise you will hear exactly what it suggests. Yes, when you order a set of tubes Upscale Audio, they will be matched. Even Gold Grade is the Ivy League: getting into the Upscale grading system results in a huge number of rejects from each batch. The testing process is time-consuming and extremely fiddly.

For example, when we test for microphony we are listening to each and every tube in a specially designed phono preamp. Plus all those rejects we mentioned? Extremely expensive. It isn't profitable to invest this amount of man-hours into every tube we sell. We do it only because we're crazy about how our own tube systems sound.

We hope you appreciate that and also consider buying all of your equipment from Upscale Audio. These are miniature dual triodes with a high voltage gain, commonly used in preamplifiers. A medium-gain dual triode tube with many names for identical variants, or others that are designed for certain characteristics such as long life. A miniature nine-pin medium gain dual triode with a very high transconductance. The is a beam tetrode, and is often interchangeable with the KT The KT88, another beam tetrode that offers high power and low distortion.

The KT and KT are beam pentodes developed for even higher power. If you find any item on our website available for a lower price elsewhere, contact us.

TUBE ROLLING & FACING ROBOT

The rolling machine is a kind of equipment for rolling and forming a sheet by using a work roll, and can form parts of different shapes such as a cylindrical piece and a cone piece, and is very important processing equipment. The working principle of the rolling machine is to make the work roll move by the action of external force such as hydraulic pressure and mechanical force so that the plate is bent or rolled. According to the rotation movement and position change of the work rolls of different shapes, elliptical parts, curved parts, cylindrical parts and the like can be processed. The high-temperature end of the exhaust pipe refers to the manifold part of the exhaust system of the automobile.

One of the biggest subjects within the permanently growing tube scene is dealing with tube rolling…. And it is one of the most misunderstood elements in the whole High End audio field. Confusion starts when we study thousands upon thousands of webpages or HiFi forums, were people share their tube rolling results with such an absolute claim, that some technically experienced people will raise their eyebrows — and the poor people who asked for some help will have to spend a lot of money buying rare NOS stuff on the basis of these indications to learn, that most of these spot on advices are not worth a single penny. One of the most important things with internet community advices regarding the usage of a certain electron tube, is to make clear that the asking person and the helpful community speak about the same thing. Such an application area is far away from what a 12AU7 must achieve in a splitter stage on an power amplifier. To make things even more complicated — there is no such thing as THE splitter stage, as a lot of amplifiers combine in a single double triode per channel a splitter AND a driver stage. If two people share their experience about a good splitter tube the one with separated splitter and driver tubes might come to a completely different solution than the other person who has a combined splitter and driver stage in one single tube. To cut a long story short…. Lets try to get things simplified….
