I think there is a way.? If nothing else is connected at the junction of the resistors, short the ends of the combination together and measure from the shorted ends to the junction of the two resistors.? Make sure your Ohmmeter is isolated.? You should measure 3750 Ohms.? No soldering required.

I think Roger¡¯s explanation of the reason for two resistors in series makes sense (better heat dissipation in a small space) as 2 x 7.5 k? = 15 k?, which is a common value. It looks as though they are there to alleviate Q1354 and reduce its C-E current. Before you change these resistors, are you sure they are out of spec.Without desoldering the junction and testing each one individually you can¡¯t be sure. You cannot accurately measure resistance in circuit. Roger has a keen eye and I would do as he suggests.
