Hi Heromusic,

The Telefunken EF86 was used for the U67 but there is some difference in sound and noise between them.
You may want to buy a few different EF86's and check them out.
Try and give a brand new valve a day or two to settle in.

I would strongly suggest a NOS Telefunken EF806S (selected) or EF806. Yes, it may be more expensive BUT these tubes are top quality/almost eternal and the sound is just butter. Your U67 and you will be very, very happy.

NOS EF86 like Siemens, Amperex etc. should do. Get in touch with competent dealer who can help out and eventually give you the option to try a few.

Also be sure to check the voltages when replacing the tube and make sure they are correct. That really affects the performance and noise level.

I've got too many tele EF86 spares for my 67 and would be willing to sell a couple of them. PM me if interested- I'll take some pics.

Klaus also recommends the Mullard EF86s, as well as the Siemens and Teles.

I agree. I used them in my Soundelux U95s mics and they were awesome. I tried almost all ef86 tubes you can find (including the gold lions.) Here is a place where you can buy an NOS EF806s. They are expensive, but they are reliable and will test them: Telefunken <<> EF806s / 6267

Also don't discount the 6J32P, they are a pretty decent tube, i find early 80's date code are very quiet. Cheers

I've been very satisfied with the tubes I've gotten from Tube Depot.

Another vote for NOS Telefunken EF806S

Amperex EF86 sounds great in U67

I know it's an old thread but I'm always messing with different tubes in gear. In my U67 I prefer an Amperex made in Holland. The current one I'm using is a gold label. I've compared it to Telefunken and Mullard and I have to say it's somewhere in the middle. It's a bit more open and High Fi than the Mullard but smoother and less strident than the Telefunken. My tests are done primarily for vocals and there are situations where I'm sure I'd like the added high end and dimension of the Tele. Haven't tried an EF 806S yet though, so that's something to look forward to.

Now I just wish I could find an Amperex 6AU6 quiet enough for my Sony 37A. I have a Telefunken in there now but I prefer the Amperex sound there as well. But 6AU6 tubes are so finicky for audio apps. You'll be lucky to find one good one out of 10 that tests good on a tube tester, yet is quiet enough for a mic.

Mullards

If you can coax Aspen Pittman out of his lair, he has a bunch of NOS Mullard EF86s....I bought a few from him a while back and they sound great in my 67 - very smooth and deep....but as earlier posts have said, it's hard to beat the big sound of a NOS Telefunken....I also have a vintage GE that sounds really nice - a bit more modern, for lack of a better term.....

Tele

Forgot to mention - you can try my tech, Scott Holderman in LA; he has found me several great NOS tele tubes and he was very fair on the pricing....

Thanks for the link. I've got a Russian tube in mine now. It's a tad bright. Still sounds good though.

Thanks. I've got a 50's Mullard ordered from Brent Jesse. He said if I didn't like it I could send it back. He also has stock on the Tele's as well. The mic sounds good with the Russian tube, more open top. A bit too much for some females. The ss frequency is nice and smooth but it seems above 12k I can hear some shenanigans.

The Mullard darkens it up. Great presence though. Very nice on female vocals.
