Greetings, I live near Toronto, Ontario. Apologies for long message. I recently moved my rarely used sound system from my basement at home to my garage at the cottage. The system is over 30 years old. The system consists of the receiver, a Pioneer VSX9300 and a newer average priced turntable and the older 5 disc CD player. The speakers are Klipsch (label attached). I am the furthest thing from an audiophile and purchased the system from a friend in some financial distress. When I first moved the system and set up the turntable the speakers would start to "hum" at approx. 3-4 or 10am on the volume dial. The CD would skip at higher volume. I called a local tv/stereo shop and they sent out a technician. I believe we solved the cd problem when he held the player up and balanced it with one hand we could increase volume no problem. I didn't have a chance to follow up on the final solution due to what happened next. When trying to eliminate the humming when playing the turntable he switched up some cables. When he increased volume smoke started billowing out of the back of one of the speakers. He had no explanation and ultimately left saying he will report back to shop and another technician more familiar will visit when back from holidays. Thank you for any feedback.
