Jeffc Posted April 18, 2023 Report Share Posted April 18, 2023 Hello, I have a pair of ADS L1590 speakers with the PA1 Biamps and one of the Biamps no longer turns on. I can hear it humming and getting hot but will not run the speaker. The power light also does not come on. Since these speakers are over 30 years old I am having trouble finding a repair shop in the Boston area. Does anyone have any ideas? Thank you, Jeff Quote Link to comment Share on other sites More sharing options...
