Driver Tubes 6922

Depends on the amount you are willing to spend?  I have a Lab12 DAC 1 Reference that takes 2 6922’s. I prefer old stock tubes on the warmer or neutral side with detail.  My experience rolling:

$- Amperex Bugle Boy 6DJ8 Holland (excellent value with great SQ)

$$- Amperex 6922 Holland

      Amperex 6922 USA

$$$- French Phillips E188cc/7308 labeled RT, RTC, Dario Miniwatt,Mazda=My Fav

        Amperex 7308 Holland (or USA) SQ or PQ label best

        Siemens E88cc/6922 Germany (little brighter)

Talk to and look at Brent Jessee and his website.  Very helpful and informative.  Good luck with it all.  Tom

So many…so little time and $…Cheers!

12AX7

RCA ‘50-60’s long blackplates (fav)

Mullard 50’s-60’s long plates (close 2nd)

Sylvania ‘50-60’s long blackplates

Amperex 50-60’s long plates or early short plates with large O getter

Telefunken smooth or ribbed plates (less warm)

12AT7

Mullard ‘50’s square getter (fav but rare)

RCA and Raytheon 50-60’s black plates

Brimar 50-60’s Yellow(rare) or white T series

Tungsram or Telefunken (less warm)

OK guys, Im going to give this NOS a try.

I what you opinion on where I should get the biggest impact to prove to myself one way or the other the value of NOS to me.

Options for first purchase are:

1- 12AT7's in Line Pre

2- 12Ax7's inputs for monoblocks

3- 6922's drivers for monoblocks

Thanks for your opinions.
