One of the Quad 405 amps driving my LS5/8 makes the most enormous 'bang'
through the bass unit about once a day. Wondered what it was first time I
heard it - thought something very heavy had fallen over. Now I know what
it is, it is preceded by low level hum for a few seconds then the bang - I
assume a cap discharging. Allegedly, the amps had a full overhaul before I
bought them including all new electrolytics. I suppose the power supply
ones can be ruled out since it's only the bass amp. Of course it might be
one in the crossover. Am I right in thinking it's more likely to be an
electrolytic? And presumably near the front end if it's producing a near
full power thump?
