A genuine Bad Boy should have a black base with the Sylvania brand name, triangular logo and codes stamped in green ink. Look for a vertical three digit code next to the triangular Sylvania logo. For example 210 would be week ten of 1952.

There are many rebranded GoodBoy 6SN7GT on the market (For 30-40 bucks).
Make yourself familiar with the structures of a GoodBoy:

Nope. a GoodBoy has to be a 6SN7GT.
The "BadBoy" you linked is a 6SN7WGT with high price. Take a note, and ignore that seller in the future.

@JKDJedi The one you linked is a chrome dome and not the same. Real BadBoys have 3 holes (not 2), "teeth" on the top mica and made between mid '51 to early '53. The 1952 tube is the most sought after as there is no doubt it is genuine.
I can't believe the crap I see on ebay that's listed as Badboys and are not even close.

This tube is neither a true "Bad Boy" nor a true "Chrome Dome". I hate it when sellers throw those names around as physical characteristics when the name is typically used to identify specific tubes. While 'Bad Boy' and Chrome Dome' are not registered trademarks -- not everything with 3-hole plates is a "Bad Boy" and not everything with a top chrome flashing is a "Chrome Dome".

ebay is a wilderness. I even found a "MATCHED PAIR SYLVANIA BLACK PLATE BAD BOY STYLE 6F8G NOS NIB TUBES" there.
I like the way the seller used "bad boy style"...

Thanks, quickly learning that thisThis tube is neither a true "Bad Boy" nor a true "Chrome Dome".

This guy claims the 3 hole plates are "consumer" versions of the VT-231 .

There was never a VT-231 Sylvania Bad Boy. There were JAN-CHS, but no VT-231. There was also never a WGT or W true Chrome Dome.
The true Chrome Domes were almost fully covered w/ top Chrome flashing covering approx 3/4 or more of the tube, were 6SN7GT and were made '51 and '52.
The true Bad Boy was made late '51 to early '53, was labeled as a 6SN7GT or JAN-CHS 6SN7GT, has bottom chrome flashing approx. 1/3 of the way up the bottom of the tube, has rectangular top and bottom mica with the top mica having 3x spikes on each short side of the top mica. The Bad Boy also has black T-plates with 3x rivet holes per plate and copper support rods protruding up through the top mica. **
** Some say there are 2-hole Bad Boys, but these are not technically known as Bad Boys. They can sound very much like the legit 3-hole Bad Boy, but in my opinion must have all of the physical characteristics of the 3-hole as listed above except for the 2 holes vs 3.

He didn't say it was, he said the 3 hole consumer version was sometimes regarded as "Bad Boy"Geez. There was never a VT-231 Sylvania Bad Boy. There was also never a WGT Chrome Dome.
