USD $‎49.95
The RCA 12AT7 / ECC81 preamp tube has smooth highs and solid bass.  A great all-around 12AT7 vacuum tube.  Our current stock is the black-plate, triple mica version made in the mid 1950's.  Our batch of tubes were originally made for Sperry Gyroscope Company and are labeled with this brand, not RCA.

Bulit for vocals!


Well controlled base, sharp and fast. Although the base does seem a little weak, it does not have that "oompf". The mids are warm, and sweet sounding (if sweet even makes sense).
The vocals are excellent, clear as crystal, I feel as if the singer is right next to me. The treble is not too sharp, has no roll off, is fast, and is very analytical.
Tube warms ups within seconds, added bonus.

Tube tested with:
"Blue" By Joni Mitchell
"Sahara Rain" By Antonia Forciona Quartet
"Caravan" By McCoy Tyner
"Come Together (2009 Remastered)" By The Beatles
