MPN: 12AX7ECC83

Brand: EI

Type: Vacuum Tube

Model: 12AX7 / ECC83

Auction is for two (2) fully tested NOS tubes, platinum matched pair of rare ECC83 12AX7 EI made in Yugoslavia on geniuine Telefunken made tooling machines. Please pay attention that they DO NOT HAVE ANY PRINTS!

They are real vintage NOS tubes in original boxes made back in late 80s - early 90s in EI tube factory in Nis, Serbia. (Elektronska Industrija Nis)

If you like sound of Telefunken's smooth plates ECC83 12AX7, 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 measure them on my Metrix and Tesla tube testers for plate currents and Hickok for transconductance and to make platinum matched pairs with balanced triode sections.

You can find them rebranded Telefunken, Philips and Siemens, because all three factories had 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 E83CC 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 ECC83 12AX7, just take a look at getter and how staples are faced. Diamond bottom is not proof any more ...

Nice feel
Color: Matte Silver
Feels good in the hand. It has some weight to it. I like the fact you can change out the blades. Way better than the cheap plastic disposable razors.

Great Exfoliator
Color: Matte Gold
Beautiful gold color, nice ergonomic feel and weight. I had been using disposable plastic razors, and thought I would take a chance on this more professional styled one for dermal exfoliation as well as my eyebrows. This razor is sharp, but it is easily managed when start gently, you don’t slide it in a cutting fashion, just use it on taught skin, and lift it up for repositioning. When I did my brows, there was no evidence of hair growth left behind. AWESOME! This razor comes with spare blades as well as replacement parts if needed. It has a rubbery silicone cap to slide on and off easily, but not fall off creating danger. The razor has a small accessible prong to easily slide it out for replacement. It comes nicely packed with detailed instructions. I highly recommend this for anyone wanting to take a decade off of their skin. I would recommend a professional if you have any shakiness though.

Worth it! Solid dermaplaner.
Color: Matte Blue
It feels solid in my hand. The blade doesn't seem to be all too sharp, but it works... so maybe that's for safety purposes? I like it and will stick with it for a while.
