the brandy coffee man
the smoke was likely r786 and or r787 ..both 100 ohms
h758 h759 may also be damaged .
possibly more but check those first

Take heart, you're doing fine!
I agree both are bad. You had the right methods and a good PNP would have read as expected. An OL indicates an open leg so it was trying to pass a lot of current through that branch. I don't know, good or bad on those replacements. These are the TO-66 package, like a small sized TO-3 package like the final outputs. There is a complementary pair that is in the TO-220 package so will need to be mounted a bit different. I'll try to locate a picture of when I did that. These are great parts and are MJE15030G and MJE15031G. I think the voltage rating is plenty good but if not use MJE15032 and 15033. You'll have to also get the right sized mica insulators such as these from Mouser: 532-56-77-11
Aha, found them! It was a repair of a Marantz 1030 integrated amp. I had yet to clip off the center collector lead in the lower picture. The connection was made through the screw.
