The 6C4 is a miniature, medium-mu triode approximately similar to one section of 12AU7. It is useful as a local oscillator in high frequency circuits and as a power amp in RF circuits. It is a common tube in Conrad Johnson and some Heathkit amps. We have a wide variety of military stock Sylvania, GE tubes with production dates from early 1950's to the 1980's under original and several relabeler brandnames such as Heintz and Kaufman, United, National.

This tube type was used as a reverb driver for my Gibson Falcon amp. I found that the triple mica grey plate versions sounded the best to my ears. The Landsdale black plate also sounded really good.
