Jeff>> the main-supply rail is 524VDC
That means the 300B is slightly above 80% dissipation
which is not too bad.>> possibly too much capacitance at the output.
You have about .7V ripple to the OPT.
IMO That is on the high side.
Best not used on Hi-Eff speakers.BTW It still loks like a step-down IT.

PS The C10 should be a 22uFd cap.
