As far as my brief search reveals these 'paired' resistors are no longer available - so you might have to buy 2 and possibly drill a hole in the PCB to accept the other resistor wire. Well, we could try and teach you - but this would be a steep learning curve. Yes, without verifying the state of the outputs and the driver transistors - not a good idea. And even when you have done this I feel sure you will need a DBT to assist with further diagnosis/troubleshooting. Knowing what we know now, that the emitter resistor(s) died, I think it very likely the output transistors (qty 2) are toast.
