PCF what?

I'm about to build a 20 Watts, based on 6BG6 tubes.

I look at the input circuit right now. I will use a copy of Dynaco ST70 input, but changed to 9U8/PCF82 tubes.:D

In my store, I have some PCF82 tubes, but there were some PCF802.

I can not see much difference in the data sheet.:confused:
Are there some who can immediately explain to me the difference between the two types?

Pentodes are quite similar but the 802 triode has twice the of the 82 one ;)

Look at:
