Tube Power Supply #1

So I’m working on this tube power supply and I found a way to get 300V~ by connecting a second transformer in reverse – the problem with this solution however is that I only got 2 power-terminals on it. So the road of doing it that way is closed.
Can I use 4 EY88 TV Rectifier Tubes (500 mA@5 kV) as a full-bridge-rectifier?

what the Hell – I’ll just throw in some silicon
