Default Help me source a toroid PT for 300b SE amp

Hey folks. I picked up a pair of Plitron OPT's for the SE amp. I'd like to use a toroidal power transformer to match. Could you help me choose one?

Here again are the specs for what I'll need: "The power transformer needs to provide about 640 or 650 volts center tapped at 150 mA or more, 5 volts at 2 amps, and 6.3 volts at 4 amps. A center tap on the 6.3 volt winding is NOT required. The Hammond 276X will work. I have been using some surplus power transformers that are 660 VCT. They give me about 390 volts of B+."

Thanks for your time and patience
