[Amps] Weird tubes in an amplifier

[MU 4CX250B]

When I was a kid I built a linear amp running four 6AG7s, from an
article in CQ. The author had discovered that the nominal 3W plate
dissipation of the 6AG7 could be pushed to 100W. The tubes  got
so hot the black paint blistered. As I recall, the tube life was
measured in minutes, not hours. (Those were the days when
Burstein-Applebee sold JAN 1625s for $0.25.) I'm sure some of you guys
remember the article!
