HMS Collingwood Other CV1758 exhibits

The CV1758 is a miniature RF amplifier pentode with very low filament consumption. The direct equivalent is the 1L4 as the CV specification makes clear. CV1758 would be used for portable radio equipment.

The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 43 mm tall.
