I have bad static from my Pioneer vsx 49 (not tx or txi) Elite receiver in the left channel, both A and B outputs regardless of inputs or components used. Switched and tried different components, inputs, outputs, cables and speakers with same result. Tonight I hooked up some newly refoamed CV AT10s and it played for more than an hour with just the slightest hint of intermittent static a couple of times during volume peaks and suddenly, BOOM, crackle... woofer cone protrudes excessively with loud static that will not quit even with just the receiver turned on with no components connected, Reversed the speakers; same result, so I don't think they blew. Right channel's lovely. Any easy solution?
Sorry no easy solution as it sounds like the output transistors blew out or the emmitter resistors. you will need a service manual and an multimeter to measure the resistors on or around the audio output transistors they are a low value resistor usually around 1 to 2 watts in size. Do not replace any bad , burnt or discolloered resistors around the audio output transistors as if tou do you might just cause more damage to the output transistorsor audio output stage including the audio driver stage of the amp!!!!!!
