Best reference I know of is here: http://www.audiotubes.com/12au7.htm

Just a list of equivalent tube numbers without descriptions:

 

12AU7 / 12AU7A

ECC82

CV491

5814

6189/E82CC

5963

6350

6680

7730

ECC802

E80CC/6085

B749

 

I have several of these (underlined) and have tried them at least once in the amp (with varying results).

Mullards, Telefunkens, and old American black plate tubes sound best to me.

The recent remade Russian and Chinese tubes sound noticeably worse, even in this amp.

I think if I couldn't get any vintage tubes, I'd probably not bother to use this amp at all.

Hey guys,

I'm wondering if anyone tried using Bravo Audio Ocean AMP with AKG K712,is it strong enough to fully power those headphones? Also, does it color the sound much or is it more of a neutral?

It will definitely drive the k712 but if you are looking for an uncolored sound, I wouldn't go for a tube amp.

Hi to all,

 

Joined the Bravo tribe with the V2, mostly influenced by the good reviews here and on CNET.

 

Short history first. Had the Fulla (very happy), but managed to burn it with wrong connection on the USB hub it was powered from. So upgradeitis kicked in and I went for a DAC-AMP desktop budget solution.

 

Ended up getting the Bravo V2 to get into tubes. As I was happy with Schiit I went for their Modi 2 Uber DAC (liked the extra inputs).

 

Broke in the V2 for about 24 hours (on the stock tube) and gave it a listen on my M4U1 (through the DAC using spotify and F2K with Asio). Plenty of power, nothing spectacularly musical on the performance (better than fiio E11 for sure, on par with the Fulla). So I swapped the stock tube with the first of the 3 NOS tubes I ordered (I mentioned upgradeitis rigth :)?). RCA cleartop, GE JAN 5814 triple mica and a generic made from mullard tube. So the RCA went in first.

 

Even with a few hours of breaking in (3-4 perhaps), all I can say is that tube rolling does make a difference. I will not make any judgments if it is for the best or not before I break it in even more and I do my standard tracks' test. Then of course there are the other 2 NOSs to compare :).

 

I was actually afraid of listening to any differences, because it probably means spending money to find the tube that works for me.

 

A few things on the V2. Nice aesthetics (high WAF!). It does get hot on the sinks, not so much on the tube. inputs and outputs seem sturdy enough. Overall a promising amp.

 

After more testing I will revert. Take care and enjoy the music!

Hi Guys, first post on the forum. My daughter has a bravo 2 and the blue led is not working. Can anyone give me an idea where I can buy one? Think I'll replace the tube while Im at it.

Any help is appreciated and thanks for your time.

My blue LED stopped working once also on a V3 but the power circuit should be the same. I had a USB mouse that was worn out. I removed the blue LED from that and the amp works perfectly again.

Almost any LED should work for that application. If the blue LED isn't working I would think your amp would be completely dead. Is that the case?

You can buy one at many places on line for pennies but buying just one wouldn't be practical because of shipping. A local supplier like Fry's should have them in a bag of 5 for a dollar or so!
