What have I collected for this amp so far...

1. 12au7a that shipped with the unit
2. 2 x RCA clear top 12au7a
3. Arcturus 5963
4. Sylvania 12au7
5. Brimar cv4003
6. GE 12au7a (Mullard)
7. Mullard short plate ecc82
8. Philips Miniwatt ecc82
9. Tung-Sol black glass (with another on the way)

Won't lose anything on them, and it's fun to roll. Go for it.

I bought 2 of them today, just so I have backups for the one I am using in my phono preamp - it's my favorite 12AU7 in that application. That's a great price on what is often a hard to find tube.

I have ecc82 telefunken, it become my favourite. But right now i am trying mullard , it is more to the bright side. But it still great

I'd be happier if my ZDT could use the 12AU7 also, but it needs 12AX7 and can use 5751 or 12BZ7, but it wont bias right with 12AU7 (per Craig Uthus at EC). And, I already have a quad of cryo new issue Mullard 12AX7, a quad of Telefunken smooth plate 12AX7, 2 GE 5751, 2 tung sol 5751, and one sylvania gold pin 5751 that I can use in the ZDT. I have so many other places that I need to send money that I'll pass on the Tung Sol black glass 12au7 for now.

Tough one to answer. I need to spend more time rolling with the D2000, but the Tung-Sol hasn't come out of the amp since it arrived...

Yes, it's a good price!

 

[plonter]

the black glass tung sol is my favourite of all the 12AU7's i got...I am using it right now with my EF1 and it sound really good. the regular 12AU7 tung sol is also very good and cheap also. tung sol is a great combination of warmth and high end extention.

 

[HeadphoneAddict]

Now that I have an EF5 here, I went ahead and ordered the black glass tung sol yesterday...

Do post your impressions Larry.

If you fancy trading your long-late Mullard, let me know, it would be interesting to hear one.

Has anyone asked Fang about whether the 12BH7 will work in the EF1? I tried one today in my RSA Stealth (much different amp of course), and it sounded MUCH better than the Mullard box-plate CV4003 I have been using. MUCH better. So it might be worth looking into, EF1 owners

I gave the EF1 I had to my Dad, so can't try it...

If you are careful, you probably won't ever damage the tube, but those are easy to replace anyway. Or just get a Tung-Sol black-glass, and then you will only need one tube

Is there a 'Tung-Sol 12au7' and a 'Tung-Sol black-glass 12au7', as in two different tubes? I'm looking for this black-glass version you refer to and only find it from England on ebay.

But tubedepot has this 'tung sol 12au7':

Tung Sol JTL-12AU7

I've done business with tubedepot before and they offer good service. But if the mysterious 'black-glass' version is only available from England.....

I am listening right now to the regular grey plate tung-sol (bought from tube depot) and it is really fantastic sounding imo...i also have the black glass version and it also sounds amazing but I couldn't tell a noticealbe different between them.

a question to all of you op-amp rollers...
the sound with the stock opa275 is wonderfull but if i want to further improve the sound what op amp is the best for the EF1? could it be the opa627? from what i know the opa627 is really top notch and used in many great amps, including my favourite headroom ultra micro. i really prefer to just replace the op amp without any additional plugs and extentions if possible. thanks.
