Hi
Some modern condensers are poorly made in that the electrical contact to the metallisation at each end of the metallised plastic "roll" inside the can is only by virtue of a slight squeezing during assembly. With time and temperature cycling the plastic roll gradually relaxes and without a spring washer or similar the contact pressure diminishes.
Given that condensers carry several amps of pulse current, it doesn't take much increase in internal resistance for problems to show up. This can sometimes appear only when hot, and after cooling everything comes good.
If you have a Lucas original that works - hang on to it !
