Rewired the sockets this morning.  Quite easy once you get the PC boards out of the way a bit.  The revisions also gave me a chance to clean up a bit of sloppy work from my initial build.

I'm listening to the first album on the new 6BR7's.  These tubes are super quiet - in my system, dramatically so compared to the ef86's.  The sound seems very crisp and detailed.  I'm really digging this.  Well worth the small effort.

Chris,

I wondered if you are still enjoying the 6BR7 in place of the EF86 pentodes.

Yes, I am very satisfied.  I recommend this swap: 6BR7s are cheap and the socket re-wire is simple.  My issues with the ef86s weren't too concerning (needed more burn-in time perhaps?), but the 6BR7 is dead quiet and the sound suits my taste perfectly.  I swapped mostly just for fun, but really dig the results.

So far, I've updated just about every resistor and capacitor of relevance (as described or recommended by other in various posts/threads), but I'm interested to learn more about other modifications.

Chris start a thread and outline what you have done.  Then the Bottlehead crew and others can chime in as to what they have tried.  I think this thread has covered a lot of different tweaks.  

The only one I am not positive has been explored is making the RIAA EQ components exactly the design values.  That puts the RIAA EQ spot on.  And it may have been discussed.
