I have a Bose 901 series 3 active equalizer that has a crackle in the left channel.The unit has been recapped, and all transistors in the left channel outside of one 2n3906 have been replaced. I swapped the 2n3906 with the identical transistor from the right channel (which does not produce this crackling noise) and the crackle remains.
It will disappear at certain times only to reappear after being on for a couple hours.
Looking for any advice on how to get this issue resolved. Or how to track down the noisy component.
