Two (2) fully tested NOS tubes, platinum matched pair of rare ECC83 12AX7 EI made in Yugoslavia on geniuine Telefunken made tooling machines .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 ...

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it.
The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch.
These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds.
The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!
