Leads on mid-1960's Siemens NOS CCa 6922 tubes

I have five pair (ten) of these NOS tubes and I think I can spare a set at MUCH less than the price you quoted (less than half). E-mail me off line if you are interested.

I tried the late 60's CCa in my DK (this is different that the early 60's CCa) and some other NOS and newer tubes. Myself as well as others that have heard all the tubes in mine prefer the JJ (ABout $20). This whole process took several months. Email me if you would like to borrow some of these for tryout.

These should provide a similar sound at much less cost. They were recommended by Chris Johnson at Partsconnexion:

Be very careful about these tubes. I've purchased three pair that went bad within weeks. They became highly microphonic, and two pair popped/crackled. Two were from a very reputable dealer, who afterwards decided that his entire batch must be bad. The first pair came from an Audiogon seller who has a lot of very good feedback. He refunded only 1/4 of my money. Sorry to rain on your parade, but you should know the pitfalls of the NOS tube market before venturing down that path. Be clear, I'm a big proponent of NOS tubes. You just have to know what you're buying, and from whom.

Thank you one and all. I have some angles to think about and avenues for more researching. You "goners" are f_cking too cool. What goes round....!
