Agree with Mike on the A supply. Your borrowed one doesn't make enough current to power your filaments. That is why you are hearing the 60cy hum, the A buss is heavily loaded and the filter can keep up with the load.
As for regulation on the B voltages not very critical. TRF sets don't really have anything that relies on the voltage being very stable. Superhets the B voltage for the local oscillator needs the stable as it will affect the freq.
