Can not be un-usual that people get caps blown into pieces
when we think of the voltages used in tube amps.

I am sure most tuube builders have been there?
At least once or twice?

Even me, have experieced this. Using only moderat 'transistor-voltages'.

Yes, those 500V caps are running very close to their rated power with a 374BX transformer. I would suggest stick with a tube rectifier, do not use the standby switch option (an indirectly heated rectifier like the 5AR4 will give slow turn on) and use an inrush current limiter on the centre tap (just solder one leg of the current limiter to the centre tap wire and put the other leg in to the phoenix connector on the board).

Enjoy the new amp!
