If the set's totally dead, no tube light up or hum, it's possible that the resistance line cord is open, even though it looks to be in perfect condition.
The resistance element was made of an iron alloy, that was subject to rusting open. You can still use the cord, but only use the two line leads.
I use the capacitor-reactance method of heater dropping, about 12.3 mfd for your heater string.
BTW, the 12A7, rectifier and output tube is quite novel!
