6CA7/EL34
The EL34 and it's "Americanized" version, the 6CA7, are among the most popular and sought out vintage tubes today. This tube is a pentode of the power amplifier type. It probably gained most of it's popularity as the output tube of choice in the famous Dynakit ST70 amps, but it has been around since the 1950s. It was found in musicial instrument amps, public address systems, and other types of home and professional audio systems. It packs quite a whallop in a rather small glass package, and yet, in well crafted amps like the ST70, it can image well, with a delicate airy touch and a solid bottom end. I have never heard a "bad" vintage EL34. Even those made in the late 1970s in Great Britain are wonderful tubes, easily outperforming the current made tubes of this type. The EL34 and 6CA7 are identical, and most versions have both type numbers on the label. Another British-made tube, the KT77, is also a drop-in replacement for the EL34/6CA7 family. This is an excellent, but rare tube not often found in the USA
