Model: ECC82 12AU7
Country of Manufacture: Yugoslavia
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!!!

It doesn’t stay in
The pipe keeps coming out. Not worth the money. Not sturdy to hold a top table.

Good finish, poor hardware.
Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly.
Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration.
Ended up running self tapping screws thru parts to complete assembly.

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

A Wonderful Update To A Great Old Reference Book!
Format: Hardcover
It's the Merck Manual! If you know medicine but are aware you don't know EVERYTHING about EVERYTHING! (Few if any do!) This is a wonderful reference. If you have no medical knowledge and think this will make you know what doctors know. Don't waste your money. You have to have a basic understanding for this to be helpful. This is a wonderful update to an old favorite.
