Tubes Asylum

Questions about tubes and gear that glows. FAQ

I have 2 wht boxed 6201 tubes with an etched triangle on bottom b/t pins. 1 tube has raised #6 other #16 on bottom. Wht markings usa 6201 small lettering 1 tube shows 46U other shows 50U..
They look simular to my 12at7WA mullards, but plates have straight sides and additional supports b/t plates on each side.
I don't have a close-up lens can't get a clear picture. Is this a 6201?
