Tubes with long plates tend to be more microphonic which can be good or bad depending on personal taste.Sometimes you can "tune" them just right with O rings or Herbie's tube dampers.If you are interested in reissue tubes at all,JAN Phillips 12au7 I have found to be slightly warm with excellent highs and bass.The Gold Lions have a beautiful midrange,a full and natural bass,and very good highs after about 20 hrs. of break in.Hope this helps,best of luck as you experiment!
Radiotechnique 12AU7/ECC82/6189 Sonics
Radiotechnique 12AU7/ECC82/6189... What's the sonic difference between the long and short plate versions? Is there any difference in the various years of manufacture? Which version is the "best"? Versions to avoid?
I'm exploring tubes for my DAC. So far I like the Sylvania 6189. But I'd like more warmth, without going the mushy Mullard route.
