I don't think so, I think something caused that fuse to blow. At 1.75 amps, that fuse is a bit overkill for your set. Here's why:
At 115 volts, it was rated to consume 100 watts (1946 specifications from service manual).
I = P / E , where I = amps, P = power in watts, E = volts.
I = 100/115 = 0.87 amp.
Add a little more since today's line voltage is on the order of 125 volts in most areas, and your set probably draws close to 1 amp of current.
A 1-1/2 amp fuse should be plenty under normal conditions.
Make that repairman replace any paper and electrolytic caps that have not been replaced yet! Running an old radio with 65 year old capacitors is just asking for trouble. They WILL fail, sooner rather than later.
