Just looked at the Sams for this amp. Each EZ81 has 2 plates connected in parallel, and each tube is connected to opposite ends of the transformer secondary. The resistance from each of those plates to ground is shown as 45 ohms. The AC volts on each side of the secondary is 300vac, and the resultant B+ is around 360vdc.
If I am reading the chart correctly, the design of the amp exceeds the spec on the tube quite a bit as it should have at least 150 ohms per leg of the secondary. Even an 8uf first cap would not have worked. Or am I missing something?
