Going back to the 42, with the set off you should measure 500 ohms from pin 5 (cathode) to earth and 510K from pin 4 to earth.
confused ..... too right
510k it is
it is on pin 4 of the 42 with the other end on chassis
pin 5 does meassure 500ohms
pin 4 cannot get the meter to read even on the 1meg range with Q

Oh and now the 50uf is out all together as previous suggestion
