Because my voltmeter prongs couldn't reach the farthest prongs of the transitors I was only able to measure the collector and base of 701 and 702, both on the collector were -34. On the base of 701 216 mv and 702 was 253 mv on the base. 703 was -34 on the base and -35 on the emitter. I am thinking so far they are not that far off?

Are there special leads you can get for the multimeter to read these transistors? If so where are they available? Or would you detach the board and read them from the backside solder points? In any case, its pretty tricky I must say
