i've heard good things about the sun rise II as well!
I wonder if we could pick and choose components off of a parts list, such as the board, acrylic case and heatsinks, et.al, and let us populate the board with our handpicked components...

- DefQon - between the lm317 - are nichicon muse ES , bi polar caps , very clear sounding caps.
- stupidmop - yeah very easy
i feel my bravo have all the best parts , i use tube 12AU7A sylvania 1960 r. , But use only with PC , its good amp but not the best ofcourse For me Have a lot of good things like SIZE and simply-build , but doesnt sound so good - as i want too .
I have integrated music card , but im waiting for sound blaster audigy4 - so i check then HOW bravo really works ))
i've got IRL510 too P
SOJEK88, Sylvanias are generally very good 12au7s. I have a few of them. If that is the only tube you've really listened to, though, you are missing out on
many, many awesome tubes! Each has it's own pros & cons. The reason DefQon mentioned replacing the Muse ES with pots (potentiometers or variable resistors) is that doing so allows you to
adjust the bias on your tube, IIRC. Unless those caps are providing the
perfect bias, your 60 Sylv can
sound even better.
Your amp is awesome, by the way! I am not being negative about using pots instead of caps. I would have put the caps
in the same circuits on the bottom of the board and pots on top. This gives you the benefits of both components and its only $2 more to have done it.
EDIT: I just saw the G3 in the Bay with a late 50's 5814 GE as the tube. This is much better than ANY recent Russian tube as a choice. You may get a decent valve with an Electro-Harmonix and you may not. Either way, the valve from the 50s is worth more and should sound much better (balanced, and biased properly) than any EH 12au7. By corollary any balanced vintage 6922 (that comes from one of the major players) will beat an EH 6922. In fact, I don't want any Russian tube made after 1994.
BTW, I remember 1960,
SOLJEK88... I already had my first microscope. I was 5.
