From the first cap connected to ground (The 136+v) Was 250volts!
And the other cap was 475!!!!
How much extra radiation was I exposed to. Haha ha (I'm only half kidding there).
And Is this still just a fix with a resistor? If it is I'll be glad.
Maybe I tested it wrong. But I think not.

Silicon diodes have a much lower voltage drop than a selenium diode. It is usually necessary to place a resistor in series with the diode to drop this excess voltage. Something between a 22 and 100 ohms should work. You'll just have to experiment with different values to see what resistor yields an output voltage close to what the schematic calls for. Just make sure you use at least a 10 watt resistor. Anything less will likely overheat and burn itself open.
