In Reply to: Can I use a 6414 Raytheon tube in place of 12at 7 posted by kkak66 on August 22, 2017 at 14:59:37:
Here ya go!
6414: An industrial, computer rated dual triode, virtually the same specs as the E180CC or 7062 listed above. Unlike the E180CC, this tube was made in the U.S.A. It is a more rugged build, with the Raytheon black-plate type sporting triple mica and military ratings. This tube is also like a 12AV7 and will work wonders in any 12AT7 spot, and may be just the ticket if you want to boost the gain of a 12AU7 circuit. The 6414 is getting very hard to find, but with a 10,000 hour heater rating you may never need a replacement. Discussion groups rate this type very highly for use in headphone amps. Stands about 1/2 inch taller than the standard 12AT7.
