I would suggest a smoothing cap from the junction of R12 and R10 to ground. That stage is the most sensitive and therefore needs the cleanest B+ it can get.
You could also replace R45 and R46 with two 5 ohm resistors in series and run the "ground" end of R33 and R34 to the junction between the two 5 ohm resistors of the other tube. This will force the tubes to equally share the load and thus be in balance.
