12at7 with 12ax7 tubes

Hi Rodman99999,

After I posted my question to you I checked on the 6201 tubes and did find the comaprison to the 12AT7. I went back to the Tungsol 12AX7's made for my pre and was pleased with what I heard. Though I thought the Tungsram 12AT7's had better detail it was the gain I missed as you know is less that the 12AX7's. I'm curious as to what the Sylvania would sound like in comparison to the Tungsram tubes I have. Know doubt the gain isssue would rear it's head but----. Have you compared the Sylvanias to any other 12AT7's? I'll be checking back later today.

The ones that I have are actually labelled, 'Telefunken' but were obviously made by someone else(no diamond on the bottom). I never had another tube in the amp, and so- have no valid comparison. The mention of Sylvania's 6201 was part of the quote, and general info, from that site. Sorry if it misled you.

No worries Rodman99999. Not to change the subject but I posted a thread in reference to a cap upgrade for my symphonies pre. Any suggestions?
