What is the wattage of the Philco 38-690 radio? How much AC current does the radio draw while operating normally. 

Thanks,

My guesstimate is 150W or around.

The 37-690 is 275W

And in case you need to know audio output power, it is 20 watts.

 But doesn't the 37-690 use power triodes in the amp as opposed to the 38-690 that uses 6L6Gs which are beam power tubes? That may make a difference somewhat, but for the same of argument I would guess it's at least 200 watts since a 1950s TV set, with a similar tube count, would draw about that. To get the amps divide the Watts by the line voltage, 120 or 117, and that will give you the amps.

I found on the internet the label on the radio which shows the radio is 275 watts @ 115 volts giving 2.391 amps.

I tested mine at 110 volts and I get 1.9 amps. So right around 210 Watts rounded up. This doesn’t take into consideration peak current when it’s being pushed. But you get the general idea.
I built a bucking transformer using a 3 amp 12.6v transformer. I run around 121 volts normally, so half the winding is fine.

Is your set a 60 or a 25 cycle set? Every set I have run across that is rated at 115 volts is also a 25 cycle, unless it's a 60 cycle one where they give a range, such as 115-125 volts, 117 volts is typical.
