They all appear intact, I have a multimeter. Any way I can test this idea?

OK - so we know we have a problem - I am OK with my working on my equipment -
But I am not Good Technician-
My experience with caps - if they blow - they either burst along the rupture panel - Axial Electrolytics, or there is Foil every where (catastrophic) -
Some times the top of an axial electrolytic can be raised - did not quite rupture - but the unit is bad...
But these are somewhat subjective - excepting the foil confetti - which from your pictures did not happen-
testing caps is harder - capacitance meters are notorious for drifting - and usually not an option on most Multi Meters- They are also Very hard to accurately test as installed in a circuit.
If you are comfortable w/ a soldering iron - you could pull the leads for the transformer and test the transformer - but not having the schematic, or its characteristics - I can not advise you on the values to look for-
You might need to find a technician-
I originally mentioned caps - as the usual culprit w/ older equipment is electrolytic caps fail - they can fail open or to a dead short - open not so bad - nonoperable - but no other damage
Dead Short - and they can take out other bits - Transistors, ICs etc...
Good luck
Does that resistor look a little toasted? The second one in from the right that is parallel to the output transistor board.
My money is on a blown output transistor. Seems like a simple board to work on.

I see then one, but the board is so gnarly, it might just be dirt. It probably wouldn't hurt to clean things up a little!
