Problems with Siemens CCa 6922 tubes?

I have used three different sets of Siemens CCa tubes in my amplifier, and all have started to fizzle, crackle and/or pop within a few weeks. Just curious if others have had this problem? My dilemma is that I LOVE the sound of these tubes, and everything else I've tried in this amp (Amperex, Ediswan, Siemens non-CCa, Sovtek, and a couple others) does not sound nearly as good.

Thanks for your feedback and/or suggestions for alternative tubes.

E288CC is not a direct substitute for ECC88/E88CC/E188CC. Best to check with Audion prior to trying one (the added heater current draw may damage the amp).

I owned an Audio Silver Night 300B SET stereo amp for a couple of years, but am not familiar with the MkII.
