I’m assembling a battery eliminator with some spare parts that I have to power filament and plate voltages for home brew experimental regen radios to build. Can any forum member suggest an all around resistance value and wattage for a bleeder resistor for my circuit below?

I did a quick chatgpt4 question on this. If it's correct, and there is no guarantee that it is even close, then the resistor is huge. I'm not an engineer, but here is the AI answer It's fun to try AI
"To calculate the resistor value and wattage required for your power supply, you will need to know the desired output voltage and current. Assuming you want to limit the output voltage to 120V DC and the current to 1A, you can use Ohm's law to calculate the resistor value:
R = V / I = 120V / 1A = 120 ohms
To calculate the power rating (wattage) of the resistor, you can use the formula:
P = V^2 / R = 120V x 120V / 120 ohms = 120W
Therefore, you will need a resistor with a value of 120 ohms and a power rating of at least 120 watts to limit the output voltage of your power supply to 120V DC and the current to 1A. "
