Hi I am thinking of buying a variac to slowly power up old vacuum tube ham radio transceivers capable of up to 200W or RF output power.
Now I do not have any other specs other than that so I need to find out roughly (allow for a safe margin) the power of the variac I need.
I have also seen digital variacs, obviously I am talking about a real autotransformer, cause I am going to test radios and noise matters.
Input voltage is 230-240VAC here. Some sellers specify KVA, some VA and some W. I know my specs may not be very clear, but could you give me a rough estimation of the values in these three units to look for to test this kind of gear?
