Need Short List of Tube Manufacturers


There seems to be a long list of tube manufacturers, from all over the world. I am retubing a CJ PV10AL preamp that only uses two 12au7's. Please give me a short list of manufacturers to either look for, or stay away from.

The two best 12AU7's are the Telefunken and the (replacement) model Amperex, bearing the name 7316. The Amperex is not a direct replacement for the 12AU7, but I have used it in a number of components, and it is terrific. The Telefunken is beautiful in every way, and is difficult to find fault with in the sound department.
I highly recommend Jim Grimes at Daily Electronics Corp.e-mail address:daily@worldaccessnet.com, 1-800 346-6667. I bought some NOS tubes at a great price, good service ,excellent tubes.
