Hello!
I want to build an OT for a class A power amplifier with PCL85, and I need to know which is the appropriate load impedance for those tubes... I haven't found any data yet...

A PCL85 translates to a type 18GV8. A 6 volt filament (6GV8) is an ECL85. Start by researching these alternate numbers.
This is an odd tube meant for TV frame output and rated for pulse output not continuous class A. Data sheets can be found here: electron Tube Data sheets - P .
amp with PCL805
A very informative write-up on PSE build with PCL805 (in German but easy to machine-translate and loadline graphs are there). A nice twist is that instead of using 2.5K load for PSE the fellow found a 10K line with a higher voltage and stayed with the same 5K OPT.
