Thank you both for the feedback. My amp is an Audion Silver Night MKII, a 7W SET amp. I've purchased the Siemens from two different sources, and the second source that I've used is honoring the warranty and replacing the tubes.
This amp is self-biasing, Albert. It has a single line input and a volume attenuator knob--a pseudo integrated, I guess you might call it.
I'm sending this current pair back today, and switching back to the stock tubes (Edicron...YAWN!) until I get the replacement pair of CCa's.
I should note that the fizzle/crackle of the tubes would probably not be so noticeable if I was using a less efficient speaker (our Klipsch La Scala's are 104dB), but we love them too much to switch. I just wish I could find some reliable tubes that I love as much as the CCa's.
Thank you both again,
Howard
