Those caps should do just fine. They won't see voltages anywhere near 50 Volts DC. There's nothing sacred about the 40-ohm value of the power resistor. I would put a 5k ohm trimpot in series with the 1k resistor in line with the transistor's base lead. You need to have a way to set the actual current draw of the RF transistors with no drive. Using a trimpot should give you some leeway with the resistance value of the 10-Watt resistor.
