CV1567 / DET25 triode
The CV Register indicates that the CV1567 is based on or equivalent to CV1025; the EVS sheet for CV1025 indicates it is a DET25. This valve carries both DET25 and CV1567 part numbers.
*: At Va=1200, Ia=30mA
This valve was developed from the DET1; with an M-shaped filament giving better mutual conductance the grid and anode are far wider in cross section. The anode is carbonised nickel.
