As I mentioned in my first post, it is not the type of tube that matters as
much as wether that particular tube (in your case a 12AU7) is a good
sounding tube or not in it's own right, and complements your setup and
your tastes; as long as that variant works in a particular circuit, of course.
I find it more than a little silly that someone would suggest that 12AU7's
as a group improve bass; it's simply not the case. Having said that, the
right 12AU7 can sound very good in V3. I sometimes use a German
Amperex 12AU7 in V3 and it sounds excellent, with a very refined and
smooth, detailed sound; although not as full-bodied as my Tele 12AX7's
nor Raytheon 7025's.
Another example: I don't know how often I hear guys say that 5751's are
the ticket in this phono stage. They then go out and buy inferior 5751's,
and wonder what the hoopla is about.
BTW, the lead bars are for dampening. I never considered that they may
be help shield RFI. They just might especially considering I don't use the
cover. Regardless, I find them very effective in really tightening things up,
and improving definition.
