12AT7 tube

Glory,

Sorry to say they are just the 2 micas...I've been chasing(trying to obtain via ebay, various sellers) the current 4 blues I have for a good 18 months...haven't seen a 3 mica yet.

All of mine (two separate purchases) came out of Germany.

Fish,

A 3 Mica matched pair just sold with the option to buy the second pair at winning bid on the Bay.

Ain't it always the way...I stopped looking once I got the three in the mail last week.

I just check the auction. $138/pr is a reasonably rightous price for these tubes. Certainly higher than the 2 mica version. but no surprise I guess. The other completed auction from a guy in GB...$213 a pair(2x mica)..ouch! & someone went for it.

If you can find a pair at a price you're willing to pay I think they're worth the effort. If they aren't for you they'll sell in a heartbeat. If memory serves this is also a 10,000 hour tube.

Not sure if this helps, but when I had a Lector 0.6T CDP I tried both Sylvania Gold 6201 and Telefunken ECC801s. In my set up the Telefunkens were the better choice for the Lector. There was an easily discernible difference between the two with the Telefunkens being more neutral and having better separation with a better soundstage. I found the Sylvanias to be somewhat less detailed and a bit forward in the upper mid-range that just didn't sound right to me.
