One perfectly matched pair of genuine EL34 / 6CA7 made by Mullard, Blackburn in 1974, Xf3 codes. 


They are from service packaging of 50 pieces and without original boxes for every single tube. Top mica spacer with 10 support points, folded plates (stapled), two slots on plates, black base with central hole in guiding pin. 


I have few 50 pcs service packagings of these tubes (all same date codes!!!), and all pairs I have are carefully tested and matched by plate current on my Metrix U61-B tester. Due to big number of tested tubes, they are matched within 5 or less%!!! These are very strong examples, selected from big number of the same batch tubes!
This is a private listing and I do not give a warranty about the quality of the valves, and I do not accept returns. These valves are carefully matched and they are 100% in perfect working condition, I simply can not take responsibility for some users who do not know how to change tubes in their amplifiers.

If you buy any item on ebay from me and for if you are not fully satisfied for any reason or have any complains, please send me message before leaving negative or neutral feedback or opening a case. I really do care about your satisfaction and I’ll do my best to solve any kind of problem.

The perfect ball for a small to medium dog.
Style: Ultra, Size: Small (2 Pack)
My dog's favorite ball. Perfect size for playing catch and return for a small dog. She loves to chew on the ball. Very durable she has not been able to shred the ball. A great entertainment value. This ball does not squeak.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣

The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.
