The DET19 from M-OV is labelled Osram in this exhibit. It is a low power VHF transmitting double triode that would have been used in push pull with a common tuned anode coil connected across the twin top caps. The HT would be fed into the tank circuit centre tap. The base is ceramic for better resistance to heat and moisture.
We have another valve that carries both the M-OV DET19 and the UK service VT61 designations.
The classic envelope is 43 mm in diameter and, excluding the UX7 base pins, is 110 mm tall.
References: Datasheet. Type DET19 was first introduced in 1938.
