I’ve just been rebuilding my Pro-next 1xpression with a granite plinth. It’s worked fine for a couple of weeks but today has developed a loud hum through the left channel. When I swap the inputs at the amplifier the problem switches to the right channel. I’ve tried my daughters turntable through the same amp and it works fine. The amp is an Audiolab 8000A which I’ve just had serviced and new input sockets installed by Kevin Green. Any ideas as to what to try next?
