Although it's easy to criticise from afar, I think it's fair to assume the designers knew what they were doing. Obviously the unit worked well enough originally.
The various vintage forums are full of threads about these old cartridges degrading and post #29 suggests that the amplifier is working well, so a replacement cartridge is surely the next course of action?
When the output from the cartridge is at the correct level, there's every chance the hum will be much less objectionable because the volume control will be at a lower setting for the same audio output. Some hum was usual with these sorts of machines anyway.
Regarding earlier comments about rectifier reliability, I nearly always have to change them in Hacker Mayflowers, for what that's worth.
