In Reply to: Hitachi 6SN7GTB question: Top getter vs bottom getter tube posted by Amphead on May 7, 2017 at 15:16:56:
Don't know what to tell you about sound difference ( different or not ) as far as getter placement. I have never designed a vacuum tube. I can say that I have rolled just about every 6SN7 tube ever manufactured. Most in the same preamp. The same brand tube with different getter placement did, have a, different sonic signature. Couldn't say whether that actually is the getter, the composition of the rest of the metal, size of bottle, etc, that makes the difference. I simply know that there is a difference in same brand tubes with different getter placement. Therefor I made my notes by where the getter was. Seemed the simplest way-
A note... Raytheon 12BH7 had a definite different sonic signature. Depending on if they had a square getter, or a round getter. Go figure
