Raytheon tubes

I don't recall seeing etched tube types on any of the Raytheon tubes that I've used. Doesn't mean there aren't any.

Besides, I haven't had a Raytheon 5814 or 5814A in a long, long time. Maybe 20 years. All the 5814 and 14A that I have are CBS-Hytron variety. My Raytheon 9-min mini stash includes 5751, 12AX7A, 12AT7WA, and 12AU7A.
