The second post by me outlines a detailed report on some of the 12AU7 tubes I have tried in the Sunrise Amp, the Sunrise amp and the Bravo are similar (the Sunrise a slightly more superior one) both able to tube role 12AU7 tubes. Also changing few resistors on the circuit for trim pots is an extra option but is not necessary, you can simply take out and tube and tube roll another one and it be fine. O getter, long grey or black plates pair best with the Bravo after the mod's I've mentioned are performed, I don't remember the sound of a stock Bravo V2 so yeah.
The cost of mod's won't involve more than a few hours and roughly $15-25 max, cheaper if you already have extra part's such as capacitors lying around, of course one can change every resistor and components to high grade audiophile one's and the modding ceiling to the sky with unlimited amount of options, but this is the same for other amp's as well bare that in mind. Just for a comparison, my Bravo V2 tube amp performs better with an array of headphones I have with different genre's then the $180 Hifiman EF-2 tube amp, and there isn't much more mod's for that amp as well.
By the last bit I meant the treble sound either too bright or recessed, I tried shortening it into one sentence so ya, bit of confusion lol.
... I see that you build Tube Amps, I do not have the skill to mod hard ware... I am NOT a DIY guy... I might like to be but right now... NO MEGUSTA. SO what would you charge me to well sell me a Modded Bravo V2 , it's about $70 stock and let's say $30 for the upgrades... then add like
Oh you live in Austrailla... well that sux.
Still other than Tube Rolling I don't have the time or skill e.e [I have a friend that does ironically] still this is my first Tube amp then I'm aiming for a Hifiman EF-5 Tube or something in that price range... so I only really want Sub $100 tube tbh... I might Roll the Tube if I get kinda broke... but I don't aim for this to be MEGA Transparent just a nice intro into the Tube Sound, until I get mah Check in le Spring, which will allow me to buy some SERIOUS gear
