Default Possible faulty AF127?

Hi
I am in the process of repairing a Roberts RT8 which was not working when i bought it.I replaced both transistors in the I F unit with AF 127s after which the radio worked. But the radio packed up again.After checking the circuit again i removed both transistors and checked them on the diode function on my dmm the base to emitter on one of them is .149 and base to collector is .247 which indicates to me it is faulty.The other one reads b to e .306 and b to c .248. I would like someone to confirm my findings before replacing it.
Thanks Terry
