On the schematic, it says "Power consumption 85 watts." That's a nine-tube radio, so it'll pull a lot of power.

Use this calculator http://www.sengpielaudio.com/calculator-ohm.htm to calculate the current based on Ohm's law. Fill in your line voltage, roughly 120 VAC and the power, 85 watts, and it will calculate current for you. It's about .708 amp.

Someone on the forum might know what size fuse to use for this amount of current. Except for the power-on surge, your steady-state current will probably be a little less than this calculation.

All my larger Philcos are rated between between 60 and 70 watts. They pull between .4 and .5 amps, measured with an ammeter. I use 1 watt slo-blo fuses for all. Some guys use fast-blo. You might have to buy several values of fuse between, say, 1 and 2 amps to see what works, unless someone else can give better advice than I can.
