CV2024 heptode
 |
This valve measures 59x17mm
overall and has tags welded to the pins, plus an extra tag connected
to the central spigot. |
This is a modified CV453.
See also CV4012. Note that this valve was originally
marked CV453 and this has been lined out; it still carries the 6BE6 markings
but of course the base has been modified.
