Something else to have a look at is the plate voltage on each of the RF amp tubes (pin 2). If you don't have any on any of the tube the RF coil primary is open (common problem with these older TRF set) Easy fix is to remove the coil from the chassis, remover the open winding (the smaller one) and rewind it with 50 turns of small magnet wire 32-40ga is fine not all that critical.
