TECHNICAL DATA
TAD EF86 / 6267 Premium Select Low Noise AF Pentode
The TAD™ EF86 / 6267: is a glass envelope miniature pentode for high-
quality small signal amplification in sensitive input stages
The TAD™ EF86 / 6267 is likewise suitable for many High-End-Audio
devices and microphone preamps as well as the famous VOX AC amplifier
line from the early 60´s.
The TAD™ EF86 / 6267 is a faithful reproduction in shape and tone of
yesteryears EF86´s.
