Hello Valve/Tube enthusiasts.

I am trying to determine if a tube that I have could be a DBM6A. 

My only Taschenbuch zum Röhren-Codex is later than the 1948/49 editition from which it was listed and this later editition  does not list it.  Ferranti data is scarce for the earlier types.

If someone has the 1948/48 edition and could advise the base and any other details, I would much apprecviate it.

Thank you and best regards,

Roy

Thank you very much to the kind members who sent me details from the Codex.  It seems that little information is known about the tube. (Or possibly one of the Codex errors?)

I have an octal tetrode  tube with top cap to g2 and very weak writing "...M6A.." under a previous metallic coating. . .  

It will remain an "unknown".

Thank you again for your kind help.

Best regards,

Roy
