Yes - I would agree! If replacing C38 and fitting a new resistor doesn't restore proper operation then my next suspect would be the capacitor in series between V3 anode and the coil L31 (which from memory together form an 'IF trap' of some kind - wasn't it to keep an Irish broadcast-station on 566KHz out of the IF stages?)
A failure of either of these capacitors will essentially short one side of R42 to earth - and with several hundred volts of HT on the other side of R42, smoke is inevitable!
