Platinum MP E188CC Valvo 7308 RARE Curved D Getter NOS NIB: E88CC 6922 7308
One platinum matched pair ( 2 tubes ) E188CC Valvo 7308, Red Logo and Printings, RARE Curved Dual Stage D Getter, gray shields, gold pins.
Made by Philips in Heerlen tube plant in 1960, VR1 Delta0C etched codes.
This is Holy Grail of E88CC 6922 CCa 6N23P ECC88 6DJ8 E188CC 7308 tubes.
I had few dozen of them, they are all from the same batch as shown on the photos, but not all original boxes have survived. This pair comes in generic Valvo boxes, as shown on photos. I can also send original boxes, but it's too risky to store the tubes in them, they are without top flips, or with top flips separated.
They are close serial numbers, the same etched codes and the same 12J codes printed on each tube. They are really closely matched, tested with 100V on anodes and -1.5V on plates on calibrated Tesla BM215A tester and the results are:
(19.0/20.0mA) (18.8/19.5mA)
These are real gems, low noise and microphonics tested in RIAA preamp and nicely selected and matched from big batch by plate current.

Our dogs hurt their mouths chewing these bones
Color: Purple & Blue
I don't do a lot of reviews because I realize many are objective opinions. However, in this case I felt it was necessary to warn others. Our dogs are aggressive chewers. Their last rubber bones (not these) which we've purchased before, and recently purchased again, were destroyed quickly. Chunks of rubber came off the ends. Since those didn't hold up like they used to, I found these harder bones hoping they would last longer. They were able to gnaw into the hard plastic within a few minutes. This created sharp edges that cut their mouths. When I saw a bit of blood on the bones, I took them away from the dogs and threw them away. I wondered why they quit chewing on them after being so excited at first. Also, these are hard enough to damage a tooth.

Pups have shown zero interest in these toys….
Color: Purple & Blue
I would agree that these are indestructible being neither of my dogs have shown any interest in these at all. At this rate they should last forever…

Durable but losses interest
Color: Purple & Blue
My dog is an aggressive chewer. She was interested in this toy while it was new, but soon after lost interest. Good news is although it took a beating it did not break or splinter. If soppy toys are disposable in your house, give it a try.
