Re: Need help identifying a 12AU7 tube

Need more info:
What color is printing on tube?
Are plates long or short?
Are plates ladder/box type or 'bump' type (like GE 12AU7A)?
Is the stopsign at the top of the sides of the tube or upper middle?

I have several different brands of tubes with the stopsign/12AU7 and the horseshoe getter w/blackplates. Any more info would help greatly.

Regards, Larry
