:No schema . . . .and I can only tell you of two tubes used in the unit.
:
:
:
:The set uses a 7 pin miniature EZ90 or 6X4 tube for its rectifier tube.
:
:
:Being physically placed near the sets power transformer.
:
:
:
:
:
:
:
:
:And the set uses a larger . . .octal (8 pin . .IF all of its pins are included) for the sets audio output tube.

Thanks Mr Edd,

The tube that's missing is the rectifier but on the display the base is similar to the one of the 6V6G, and that is my doubt... :(
The remaining tube are miniatures (6J6, 6BA6, 6AT6).
My doubt is that if an equivalent with a diferent base won't burn the remaing tubes??
This layout that i've got fits almost perfectly on the 850V but is of diferent radio (857 RTV), and i'm afraid of burning the rest of the tubes...

Thanks,
Miguel Cardoso
