PCL805 were common towards the end of valves being used in the frame stage of B&W TVs. I understood at the time that they were improved versions of the PCL85. I suspect the same applies to the PCL806 just being a later version of the PCL86.
PCL82 and PCL86 were commonly used as audio output valves and PCL84 were used in the RGB (R-Y. G-Y, B-Y) colour output stages.
