No. Only the phono stage tubes are grounded, just as it's shown in the schematic. BTW the voltages on the rails are about + and -11.5 volts. The 12AT7 and 12AX7 require about 12 volts when using pins 4 and 5 to supply heater current.However, you might want to measure the voltage across V5 - depending on the filament resistance of the panel lamp the voltage across V5 can be above spec.
I also recommend (and furnish in my power supply kit) 3.6 Ohm 3 watt resistors in the heater supply to accommodate today's higher AC line voltages.
Edited to add voltage info.
