I'll post some pictures later in the week, but while making a tape of Sibelius Symphonies and a mix of Yes songs, I discovered that the Phono section of the Sony STR-GX90ES is malfunctioning. Only one channel is outputting a signal. I don't listen to a ton of records, but enough that this will be a nuisance, especially since I had planned to leave an all Sony ES set up in place for a few months. I can open the hood but given my lack of skills there is very little i can do on my own unless there is an obvious problem. At this point I'll be it would be cheaper to take an electronics class than it would be to ship the machine and have the problem repaired . . . any suggestions?
