Country of Manufacture: Yugoslavia

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 ...

Why didn't I find this years ago?
With my excema, I fought for over a decade to find a product that will help. This lotion is amazing. I put it on after showering. It goes on easy, it soaks in well and for a gal who is almost 60 my skin now looks nourished, healthy and like I'm in my 30s and soft. Using this with the balm, my excema patches are almost completely gone. Love this!

Ok to use to prevent flare up
This cream works ok if the skin does not have a flare up. If your kids skin is irritated, I wouldn’t recommend to use. My kid would get very itchy and wouldn’t want to use if her skin had an eczema flare up. More to prevent rather than help reduce flare up

Glad I tried this lotion
Lotion is really nice and has a very light fragrance which I appreciate. It is gentle on sensitive skin (no issues so far after using about a week).
