It is a double sided board.
I would just remove the resistor and put in a 1/2 watt in its place. Also, check the transistor (Q14) to make sure it didnt sacrifice itself also.

can you give me some help i have popped R141 ,whilst working a station near Inverness who gave me 5/8/9 ,
Then Smoke !! luckily R141 let go ,
I would like to replace with a bigger value Resister by drilling 2 holes through the board to support the Resister with solder..
My question is : is the b40 board single or double printed circuit, my unit is shoehorned into its cabinet i don't want to pull it all out to find out ,
and don't want to do any more damage,
