Blown up, split in 2 finals?

Nah; that is the voltage regulator..
Can you take another picture just to the left of that one - near the rear right corner?

After desoldering, I got nothing but zeros or open on diode mode. Might be a little problem there.
Two failed finals and a blown AM Reg? You might have gotten an indirect strike. But if that is the case, if you replace the tip36c and something else fails shortly after that; then it was an indirect strike.
I've only had the opportunity to work on a radio that had an indirect lightning strike, and had to fix more than a few things on it.
The tip36c is a cheap and plentiful part; but don't buy a poor quality one, since it will be running pretty hard when in AM.

This is the exact reason I have always shied away from an electronic repair. I search a simple part number, and I get 100 matches. How in the world am I going to wade through that?
I found one on ebay for $5 that the pic is the exact one in the radio. I will probably buy that one, and if it is different in any way it will be returned. Seems safe enough I guess.
Well at least you got the SSB working, good luck repairing the AM section.. Hope you get up and running soon... It definetly sounded like a lighting strike, thats why I mentioned that or a power surge at your home 20... I have my astron 70 amp hooked up to a APC S20 power conditioner with battery backup.. I have my PC and equipment hooked up to that, if I ever lose power everything will stay on for about 20 mins..
Just curious how a surge can get to a radio? Is it though the ground? Or neutral through the ground, or jumping the hot switch? I guess I don't really know how a surge could be much of an issue, unless the power supply was switched on at the time.
Assuming you have at least 1 ground rod by your antenna, try one of these pictured below to protect against nearby strikes and static discharge. I use this clamp and polyphasers for all 3 of my antennas. This breaks the coax connections before entering the shack. I have 3-8ft ground rods bonded together with this clamp on 1 of them.
Also use a quality surge protection power strip. I use TrippLite power strips because they have the better reputation for quality over the Walmart cheapies.
That should protect you from what you just experienced. With a direct lightning strike, I wouldn't guarantee it, I would be more concerned about my house not catching fire.
The clamp and polyphasers are sold separately.
