Sorry about the confusion re EBC but you apparently figured it out.
Here’s what I get from your data: The junction of R30 and R31 should bias the bases of Q4 and Q5 to about 2.6 volts however the bases are running around 7.8 volts. Also the base to emitter drop should be about +.7 volts but it is -1.2 volts. These transistors are biased off most likely due to a bad collector to base junction on one of these transistors. There is an outside chance that R31 has opened but that is rare but you should check it with an ohmmeter just in case.
Since Q4 and Q5 are essentially in parallel to DC it is not possible from the data to tell which is bad but considering that this could be storm damage the most likely “blown” transistor is Q5 since it is attached to the antenna. You may also have to replace Q4 but start with Q5. Since the modulation takes place in these transistors this could explain the bad audio you reported.
It is possible but not likely that Q2 is damaged but judging by the BE voltage and the fact that the collector is apparently drawing a controlled current it is probably OK.
The best way to replace transistors without damaging the board is to cut the leads at the body and remove the leads one at a time from the board with a soldering iron. Usually if one tries to get all three leads hot a once the board will be damaged.
The 2N2222s used here are very common and Radio Shack should stock them. Also, pick up a spool of Solder Wick or a similar product so you can clean the old solder from the board without damage. This is a braided copper flux coated wire which works much better than a “solder sucker”.
This may be more detail than you want but it sure is a good learning experience….after all, you now know about EBC.
Be sure to report back when you get it working.
