Bravo Audio - funny looking little tube amps - Page 177

post #2641 of 2643

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.
