The 6064 (special quality) version of the 6AM6/8D3. The 6064 usually is deemed equivalent to the CV4014 but the direct equal to the CV4014 is the M8083 and these are specially designed to withstand vibration.
The 6064 is a high gain, high impedance, variable mu, screened pentode. It could be used from AF to VHF up to about 200 MHz and was found in large numbers in most types of electronic equipment. In RADAR, radio & TV it was used for RF and IF amplification. It was also used for oscillators and frequency multipliers.
