Crack resistence check, getting above 0 ohms on terminal 6 and 8

[Paul Birkeland]

Those diode leads sticking out around terminal 19 (where the red wire goes) need to be trimmed back.

The diode going to A3 looks like possibly it's installed in such a way that the leads coming out of each end of the diode are touching, which would also be a problem.

None of this will make a part hiss.  If your resistance checks are still OK, then I would attempt to measure voltages.

Ok, those fixes shouldn't be too bad! Also I am currently feeling some heat coming off the capacitor connected to terminals 20 and 21, I tried to measure the voltage earlier but it sparked, should I be concerned about this/is there a way to get the current out of this capacitor?

With the amp off and discharging, if the voltage on the unbanded end of that capacitor is much different than the voltage on the unbanded end of the other 220uF caps, that would suggest a loose 270 ohm resistor or a loose black wire back there that is preventing it from bleeding down properly.
