Make sure your points are clean and the cap is dry inside!
Why do today what you can put off til tomorrow.

I would guess that it has nothing to do with your condenser. Sounds to me like the advance is sticking/ not moving as it should.  That or the shaft is sloppy in its bearing.
 
You can take hold of the rotor and see how easy it will moves the advance if at all.

Could be a bad spark plug. A misfiring plug will allow unburned fuel to enter the muffler and ignite making the explosion. Combustion is supposed to take place in the cylinder, not the muffler... LOL!
