I have an old 3-speed Phillips turntable which was bought in 1974. It recently has stopped giving output in one speaker. The mechanical parts work but the electronics in the Left speaker seems to have given way. I took it to a repairer who said that the left channel preamp is not working...
Recently I acquired a Technics SL2000 turn table. When I tried to play it, only one channel is working . I am new to TT's and I could not find much help online which describes the same problem .I am not sure where to start my debugging any help is highly appreciated.
