One thing I would be concerned about in the driver stage is the heater to cathode voltage. The 6SL7 max cathode-filament voltage is +/- 90 volts, and if the voltage is divided equally between both sections the upper cathode is sitting around 140 volts whereas It looks like the heater is grounded so that is a recipe for premature tube failure.
