The CV1076 is the UK procurement code for the commercial DA41. Our other CV1076 has a carbon anode but this has a metal anode.
It is a magnificent audio triode that was designed so that in class B a pair would deliver 175 Watts at 5% distortion. The anode dissipation is 40 Watts.
The reverse shows that this is a production DA41.

The classic envelope is 51 mm in diameter and, excluding the UX4 base pins, is 137 mm tall.
