Thanks for the advice everyone.
tube advice 5687s
Any recommendation on 5687 tube for a RSA B52 Preamp/Headphone amp? (These are the tubes that drive the headphones in this amp.) I am looking for softer, less prominent, less forward sound in the lower treble/upper midrange. I now use TungSol/Raytheons, which are nice,
but my headphones work better with with anything that reduces glare.
(I have found that Telefunken 12AU7s are the tube of choice for the
gain-tubes in the B52; they hold back a little but let you see into the space.)
There doesn't seem to be a lot of choices among 5687 tubes,
from what I can see. Thank you in advance for any advice.
