Need help C-J monoblock LP-140M with Siemens CCa

I am new to the tubes world and this is the first time ever I have tubes power amp in my audio gear.

I have been used 3 different sets of NOS/NIB Siemens CCa tubes in my Conrad Johnson LP-140M amplifier, and all have started to fizzle, crackle and/or pop within a few days.

Just curious if others have had this problem? My dilemma is that I like the sound of these CCa tubes, and don't like any junk tubes (Electro-Harmonix was supply with the Amp from C-J factory) in this amp. I don't believed they sound nearly as good as Western European make tubes.

I have hear about Ediswan CV2492 from UpscaleAudio.com, is it really equivalent or better than (Siemens, Telefunken or Valvo) CCa?

Thank you so much for all your feedback and/or suggestions for alternative tubes.

I saw someone post about the dreaded "hand oil". Sorry to say but this is a load of crapola. I have tubes ranging from WE212E that will remove you finger prints if you touch them hot to a gazillion 6550s in the CJ and jadis JA-500. In no case have I lost a tube due to touching it. Old wives tales from the audio crypt.
