CV171 pentode
 |
This valve measures 123x45mm
overall and has a B4 base. |
The CV specification describes CV171 as a Vari-mu
tetrode or pentode. The example here is a pentode. The specification states
"This valve is standardised for use in certain equipment which can
accept these diverse types. It should not, therefore, be used in any new
design."
