Sorry..I misunderstood. It's the input/driver tubes that went bad not your power output tubes. So the answer is there is no bias adjustment for input/driver tubes. The bias setting is for the output tubes. Then replacing the 6922s is relatively simple and is a matter of trying out different variants to see what you like best. Good luck.
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.
