看某国外网站说国产电子管的“网屏”,望能引起注意!Warning for Fake Mesh Tubes

Last Update: 10/19/2019 21:11:49

In Germany, we have an saying: Copying of your products is the highest form of recognition. Only, when I see what the Chinese factories are doing, they use punched Anode anodes, and call that mesh. For buyers which want the optical illusion only, it's probably ok, but in case you wanted to buy mesh tubes, and get send punched Anode anodes, there is something wrong. So we speak out a warning here for this.

What is mesh?

The word mesh is by definition for things that are woven into each other. With mesh wire, this is what you get with an Emission Labs ®mesh tube. The Chinese are selling so called "mesh tubes", which are Solid Plate tubes, with very fine holes in the anode.

Some sellers try to blow some smoke around it, and call it semi mesh, which word suggests something comparable, but also this is not so. The only thing which is the same as real mesh, is the light effect. For the rest, it is a Solid Plate tube, with holes in it. So using honest language I call them fake mesh, so there is no misunderstanding. A product is made of mesh, or it is not. Same as there is no such thing as a little bit pregnant.

The special sound of mesh tubes

This can not be achieved by light effect. It can only be reached by low resonance and other mechanical properties of the wire mesh, such as the irregular surface. Also there is an electrical (and so sound) effect of very small fraction of the electrons initially escaping thought the holes. This electrical current is not lost, as the electrons are reflected by the glass, back to the anode.

The Blue light effect of mesh tubes.

This blue effect is mostly known from tubes like EL34, which have relatively large the adjustment holes at the sides of the anode. Through these holes, a certain amount of electrons will escape, building the blue patterns on glass or the mica. The EML Mesh tubes will show a similar blue haze, right opposite to the anode of the 300B mesh. Even so, it may show a shadow pattern of the anode and the middle cooler. After some use, the fluorescent effect of the glass will disappear partially. This is normal, and no sign for anything. We just want to point out here the light effect and how it will develop. Please regard it as something interesting, related to mesh tubes, but the light effect is not a product specification, and it is bit different for all tubes.

Punched Anode tubes.

The correct designation for the Chinese such tubes is "punched Anode", same as some radio tubes have, but I see no seller use this clear word. Of course, we are not against punched Anode tubes as such, but the objection is against fooling the buyer with an illusion of mesh tubes, and the sound belonging to that. The word semi mesh is misleading also, because that suggests it has something to do with mesh, but the only relation, is the optical illusion.

We do not say these are bad tubes, or anything like that. However we object against the use of the word MESH for this, because this is simple not what these are. Sorry for telling the truth here, but to speak openly about this is more beneficial.

在德国,我们有一句话:复制你的产品是最高形式的认可。只是,当我看到中国工厂在做什么时,他们使用穿孔阳极,并称之为网状阳极。对于那些只想要幻觉的买家来说,这可能是可以的,但如果你想买网孔管,得到穿孔阳极,那就有问题了。所以我们在此发出警告。



什么是网格?

根据定义,mesh这个词指的是相互交织在一起的事物。使用网状金属丝,这就是使用Emission Labs®网状管所获得的效果。中国人在销售所谓的“网状管”,它们是实心板管,阳极上有非常细的孔。

一些卖家试图在它周围吹一些烟,并称之为半网,这个词暗示了一些可比的东西,但也不是这样。唯一与真实网格相同的是灯光效果。其余的,它是一个实心板管,里面有孔。所以用诚实的语言我叫他们假网,所以没有误解。一个产品是由网制成的,或者不是。就像没有怀孕一样。



网管的特殊声音

这是光效应所不能达到的。它只能通过丝网的低共振等力学性能,如不规则表面来实现。还有一种电子效应(也就是声音效应),最初从空穴逃逸的电子只有很小的一部分。当电子被玻璃反射回阳极时,电流不会丢失。



网格管的蓝光效果。

这种蓝色效应主要来自像EL34这样的管子,在阳极的侧面有相对较大的调整孔。通过这些洞,一定数量的电子会逸出,在玻璃或云母上形成蓝色图案。EML网状管将显示出类似的蓝色薄雾,正好与300B网状管的阳极相对。即使如此,它也可能显示出阳极和中间冷却器的阴影图案。使用一段时间后,玻璃的荧光效果会部分消失。这很正常,没有任何迹象。我们只想指出这里的光效应和它将如何发展。请将其视为有趣的东西,与网孔管有关,但光效不是产品规格,而且对所有管来说都有点不同。

穿孔阳极管。

中国人对这种管子的正确称呼是“穿孔阳极”,与某些无线电管的名称相同,但我看没有卖家使用这个明确的词。当然,我们并不反对这样的穿孔阳极管,但反对的是用网状管的幻觉和属于这种幻觉的声音来愚弄买方。半网状物这个词也有误导性,因为这表明它与网状物有关,但唯一的关系,是视觉错觉。



我们不说这些是坏管子,或者类似的东西。但是我们反对使用MESH这个词,因为这很简单,而不是这些。很抱歉在这里说的是实话,但公开地谈论这件事更有益
电子管绝对是一种艺术品

看不懂

较真。。。。

德国依美声,胆管品质真系好。人家严谨的作风,就是胆管质量的保证。KR的也不能与之媲美。

非常感谢孤舟横渡师傅译文。(在下译不好这专业文字,正盼有师傅代劳)

现在正在生产的胆管,就别吹谁比谁好多少了,只要三观端正,大差不差
