999999999999,
The Siemens CCa for sale on the Gon by Stance 1 I bought. There are some pics of the tubes on his ad. Is this the tube you speak of?
Tvad,
You are a very helpful member in this community of audio nuts. Your thoughts on this tube are spot on from what I am hearing in my system.
I did have this tube at one time but my system is no where the same as it was back then. I was running it in a Audio Note dac ( God help me ) God did help me snap out of all that mess and entanglament. I am free, free, free alast, Oh, sorry I got carried away with my dileverence.
A very different sound than the Amperex WL GP PQ 6922 D getter. It takes the top end to the very limit of being to much of a good thing. It my have its toes over the line at times but you are rewarded with a very open and clear sound.
For some reason these tubes seem quiet and non microphonic. I only got one hour with them so maybe they will "break in" some.
There are no internal codes inside the tubes.
