They replace the CCa, 6922, ECC88 and 6DJ8. The build quality and durability of these tubes are exceptional. The tubes of course have the typical diamond embossing on the tube base,, the tubes have the typical diamond mark on the bottom.

Telefunken E88cc Matched Pair. Curve Traced
I have a good stash of the finest 6922 tube ever made. I will never use all that I have. This pair is new and have been curve traced by Mike at Quicksilver Audio. I’ve also matched them with a George Kaye small tube checker. These are not thrown into a. Old TV tube tester. They are gain matched in a real preamp circuit and curves were generated for each frequency. They will arrive in white boxes. Thanks
