PCF200 @ The National Valve Museum [Datasheet] The PCF200 was designed as a frequency changer. The triode section forms the local oscillator and the pentode is used as the mixer. For VHF and UHF the pentode made a better mixer than the hexode. This was probably made in the mid 1960s when UHF television was just starting in the UK. http://www.r-type.org/exhib/aai0085.htm
