The datasheets for the PCL82 (and UCL82) state that Va max and Vg2 max are 250 V, while the datasheets for the ECL82 show 300 V for these voltages. However, I have my doubts about these differences. A link to a thread about this topic:

But since the impedance of the primary of your output transformer is 5K, I think that 210 V is the optimal B+ (see post #4 in this thread).
