The CV4024 is the UK Government designation for the Brimar 6060 and/or the Mullard M8162. These are all special quality versions of the ECC81 VHF double triode.
A version with flying leads for direct soldering into circuit is the CV4033.
It was designed for RF stages, oscillators and frequency multipliers. It now finds favour for quality audio amplifiers.
The construction is slightly different to the ECC81/12AT7.

The thin glass tube envelope is 20 mm in diameter and excluding the B9A base pins, is 48 mm long.
Reference: Data-sheet. Type CV4024 was first introduced in 1956. See also 1956 adverts.
