Default Operating points for #37 triode

Can anyone suggest some decent operating points for a #37 tube line stage? I haven't quite gotten the hang of the gride line thing yet.

How about starting with the datasheet and using the 135Va-k point with say a 47k anode R? B+ = 340V, Rk = 2k2.

As good a place to start as any.

Or you could choke load it with a Hammond 156C and B+ = 160V
