Hey so I can upgrade my stock tubes with any EF95 family tube? Like the voshkod? http://www.ebay.com/itm/2x-Voshkod-6ZH1P-EV-Matched-Pair-Little-Dot-Amp-III-IV-/290613497027?pt=Vintage_Electronics_R2&hash=item43a9ea0cc3#ht_1772wt_701

The bravo's gain is way too high for the Shure840's don't you think?

Those are excellent!

Is there any modification needed...or is this just plug & play?

I haven;t a clue what I am doing!!
I have this little Bravo amp and I have bought a JAN Philips NOS Low Noise 6922 6DJ8 ECC88
http://www.ebay.co.uk/itm/370381963960?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
It doesn't work...I haven;t a clue why not!!

Because this tube works at 6V not 12V like the Bravo.

Yes!! Thanks for that...I was trawling through this thread a while age, and the Phillips 6922 6DJ8 ECC88 was recommended!! I must have read it wrong.
 I have since been looking at the  12au7 range and there are different manufacturers with different characteristics!
I have bought the recommended RCA 12AU7 A - Clear Top...also I am looking at a  MULLARD ECC82 12AU7  and the SYLVANIA 12AU7.
The set up I have is a Sony Discman D25 to the Bravo audio amp listening through a pair of V-sonic GR7 in ear headphones!

no way because EF95 and 6AK5, 6Z1P are 7 pins valves, you need 9 pins valve to use it on Bravo, Indeed, Project Sunrise, etc...
 
And yes 12AU7 cleartop are stated to be excellent valves for amps, IMO the best valves for this kind of amp are ECC86, 6N27p, etc... valves specifically designed for low-voltage audio use..

Hi all
I just bid on a pair of Pioneer SE-50 cans, theyre low impedance at 8ohms
I was wondering if anyone has tried this amp with low impedance headphones?
what could I expect if I hooked them up to this amp?
 
 
Thanks!
 
now im off to read the rest of this thread...

Don't be afraid. It won't bite. It's only running on a 24 volt DC supply.

You want terminal case of the willies? Check out Don Garber's open-frame designs.
