Brand: EI
Auction is for one (1) fully tested NOS tube, rare ECC82 12AU7 EI made in Yugoslavia on geniuine Telefunken made tooling machines .
Exceptional performer in many guitar tube amps!!!
They are real vintage NOS tubes in original boxes made back in 80s in EI tube factory in Nis, Serbia. (Elektronska Industrija Nis)
If you like sound of Telefunken's smooth plates ECC82 12AU7, you'll like these too, because they are (almost) exact copy. The only differences are in thickness of halo getter and in "staples" which are facing each other.
I have few 100 pcs boxes of these tubes and I had enough time last few months to carefully test them on my Metrix and Tesla tube testers for plate currents and Hickok for transconductance.
You can find them rebranded Telefunken, Philips and Siemens, because all three factories have contracts with EI. These are pre war tubes, with exceptional quality, made with 1st class materials, because of that many of them have been rebranded like long life premium versions E82CC and sold by Siemens and Philips in their boxes.
You can also find them relabeled Telefunken with diamond mark on the bottom last few years! Diamond bottom mark is done on laser machine, and if you want to avoid that and to be sure that you are buying genuine Telefunken ECC82 12AU7, just take a look at getter and how staples are faced. Diamond bottom is not proof any more ...
Auction is for ONE tube, not for a pair!!!

Powwer, Speed, interchangeable Attachments, but a little too much Speed.
Color: Black
Why not 5 Stars? Something a little silly, but this frother is a little over powered. Not necessarily a bad thing, but for me, I need a slower setting.
Now the good stuff. I purchased a different, really cheapo frother to see if it was useful before I bought a better quality one (more $$). The cheapo one worked fine, mixing drinks, scrambling eggs, frothing milk. However, it was low powered, and thicker items like eggs caused it to burn out. This household agreed a frother was a useful tool and I picked this one. What is 5 stars about it? Three attachments- a spring type frother, a beater, and what looks like a thin dough hook. Interchangeability. Love it. Also, three speeds. Nice to have a choice. Operation? works perfectly. I Like rechargeability. So where is the missing star? It is stuck to the wall with the hot chocolate that sprayed all over. This thing is powerful for what it is. I wanted power. But the power comes at too high a speed. Low speed should be the highest, and 2 more slower speeds would be perfect. So we mix in a larger container to keep the contents in the container and off the wall.
TLDR: Good: Interchangable whisk, rechargeable, 3 speeds, lots of power. Bad: Low speed is not low enough.
If all you are doing is frothing milk in a deep container, this works great. Has the power to scramble eggs, for example. Mixing hot cocoa mix in a nearly filled cup will bring excitement though.

I love it, it works great.
Color: Black
I received the Electric Milk Frother, EW-071, about 2 weeks age and absolutely love it. I don’t froth milk or drink coffee either. What I do, do is for years I have mixed my own mushroom drink, way before all this mushroom coffee fad began. I also mix in other ingredients, collagen, creatine, ginger powder, cinnamon, and a few other items and the coffee frothers do such a poor job of mixing them all up. The EW-071 with the Balloon Wisk does a wonderful job. It is high powered so be careful, if you totally fill the cup expect a mess, think before using this unit it is powerful. I also like the on – off buttons. With the other frothers you have to hold the button, I hate that. I do keep my thumb close to the on - off button but have not had a spill yet.
Good job. Thumbs up.
Robert, Las Vegas.

BUY THIS FROTHER! IT'S THE BEST & THE LOWEST PRICE.
Color: Black
I have had a couple of other frothers, and I really like this one the best! It has ALL the different frothing tools, and it is rechargeable, not needing batteries, which is a plus. Another big plus is that it is very attractive and has the best (lowest) price of all the others. I must have looked at 100 different brands, and this one is amazing. The different speeds are separate buttons, making it much easier than the ones where you have to keep hitting the same button to get to other speeds. My other one was too fast & the milk would go all over the place, including my clothes! This frother would make a great gift. I gave my old one to my daughter... now she's coming over this week, and she's going to want my new one. ;-)
