Sorry, but those aren't Authentic Bad Boys. Bad Boys were made in years 51 to 53 and had three holes in their plates.
Well these were bought from Brent Jessee and so far I haven't been disappointed with his tubes. These were made in 1951 and have the 2-holes. To my ears the 2-hole and 3-hole versions sound identical. I am not trying to deceive anyone or trying to sell fakes...
Cheers...
From Brent's website:
"Later GT versions were in a medium glass envelope with a green label and blackplates with bottom getter, sometimes called the “Bad Boy” 6SN7, and are sought after for their excellent sonics. The Bad Boy tubes are virtually identical to the military VT-231 from the early 1950s and are currently a less expensive alternative, but this could change as the Bad Boy fad catches on! A side note about Bad Boys, there were versions with 2 rivet holes in each plate, and versions with 3 holes. Both types sound identical. Don’t fall for the bogus story that only the 3 rivet hole types are the true “Bad Boys”! You will miss out on some great sound from the 2 hole type, since the 3 hole versions are more difficult to find, more expensive elsewhere, and don’t sound any different! I suspect the “3-hole only” story got started by my competition to justify charging a higher price for these tubes!”
