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.

These wall plates look good and work well
Style: 2-Speaker
I used these wall plates for my home theater system. They are easy to install, look good, and accepted my banana plugs perfectly. They make my installation look tidy and I am pleased with the outcome. I have used other Cable Matters products in past and have always been happy with the results.

Great...but could be a bit better
Style: 2-Speaker
Almost perfect. Easy to screw apart and insert wires to both the back and to the front, or do what I did and screw the wire onto the back and then use a banana plug for the front. My only complaints are that the back piece sits off the wall a little, so the plate doesn't fit flat and tight against the wall. It leave a little gap around the edges. The other complaint is that the back piece has some flex in it, which makes me nervous when I push plugs into and out of it. I think it probably will hold up fine, but it feels a little oogy to push banana plugs into it and see it flex. Comes with all the hardware needed. Just need a philips screwdriver and wire cutters and you're good to go. Super easy to use, and way better than the spring loaded connections it replaced.

Really good wall plates
Style: 1-Speaker
These plates came on time, packaged well and are "doing the trick". The plates, while fairly light-weight are perfect for my new system. They installed into the junction boxes very easily, hold the wires snugly and the banana plugs are perfect for my usage.
If you need a nice, easy to install, good quality, wall plate, I would highly recommend these.
