The 6067 is a special quality double triode with separate cathodes. Electrically it is equivalent to the 12AU7 but constructed to withstand vibration by being fitted with double mica sheets.
The twin triodes with internal separation but no internal screen as these are not designed for small signal RF use.
The grid is wound on copper supports.
The thin glass tube envelope is 20 mm in diameter and the length excluding the B9A base pins, is 46 mm.
Reference: Datasheet. Type 6067 was first introduced in 1951.
