A more affordable alternative to the Siemens Cca is the Amperex 7308 made in USA version. It's not a Cca but pretty close.

Hey Dennis,
I know they can be expensive but you will forget about the cost once you hear them.

Anyone want anything from Eric at CF, just threaten to share that quote with Lori Anne! :lol: :

MRHT,
Thank you for sharing your knowledge.
I find your chronology of 490t tube rolling fascinating.
The Seimens Cca do have a excellent reputation, but
are above my price range. Maybe...someday.... :-({|=

Are the Amperex 7308 tubes you mention PQ (non Jans)?

The JAN (joint army navy ) are the same tubes. You should be able to get a NOS or very strong pair for $150. Don't confuse them with the Amperex 6922 PQ which is also a fine tube but has a warmer sound. There is also the Amperex Holland made 7308 but it is also different than the USA 7308. I use the Holland's in my preamp and Siemens Cca's in my cd player. I have Amperex USA 7308 in my other preamp.

Important note, the USA 7308tubes I have heard were all white label from the early to mid 60's. I haven't heard the orange labels. Now the Amperex PQ 6922's i have heard both white and orange labels and they sound identical.

I tell ya what I would do. Just to get started with a very nice budget upgrade, try a set of the green label Jan Phillips 6922's. Here's a nice set:

Dont buy any tubes from china or Hong Kong and I usually only buy from ebay''ers with 100% feedback.
