Bravo Audio - funny looking little tube amps - Page 177

post #2641 of 2645

Well I'm finally trying my little new V2 amp.

I almost immediately changeg the stock tube. I think it sounds decent overall but on stoner rock songs the instruments are blurred and I can't appreciate the voice. Even if basses and highs are defined, mid ranges are totally killed.


I am trying these new tubes now, a Philips:



And a jugoslavian International Servicemaster Electron Tube


I can say they improve greatly the amplifier though I prefer the second one. I think it can manage better the whole amplifier.



I would like to try an RCA clear top.

I am searching ebay for some good deals and I'm seeing they use different codes to mark different kind of tubes. So, I'm just trying to understand for example, the difference between a 12AU7A and a 12AU7 and the difference between ECC82 6189 5814A.


Any tips for the newbie?


Sorry bro, was offline for a few weeks.


12AU7 and 12AU7A is basically the same tube. You will not hear a difference. I think the "A" model is just something that came out later.


ECC82 is the European marking for a 12AU7. That's all.


As for the others: there are numerous similar tubes for this particular family. The best reference I've seen to easily/quickly explain those is Brent Jesse's website here.

My first post! New to the tube amp scene. My V2 should be delivered tomorrow. Excited to try some different tubes in it☺

Just bought a second hand Bravo Ocean. However it was dead on arrival. Tested it and it does seem to the valve. Any suggestions for a suitable replacement ?  12AU7 I believe.  


Edit: working fine, looking forward to trying my first taste of valve amp with my phones.

Great little amp but I wish they'd put a gain control. Pretty useless connected to my CD Player/ CD receiver as volume is ear shatteringly loud at 1/16 to 1/8 volume.A bit uncontrollable to say the least. I cant imagine what the rest of the volume range is for when attached to a 'proper' HiFi output; the Ocean can surely drive any headphone out there !


Decided to use it as a bedside unit fed by by iPod Classic or Sony A15 (which has a particularly feeble line out) and it seems great for this purpose whilst looking pretty cool.
