Thank you for your responses. I am using a 22090 transformer and my track is hard wired every 4 sections with 14 gauge wire to the buss. Yes, that is an after market speaker I purchased from portlines. I will double check with Doug Peck. Of all the things I've done to make my layout great, I never inspected or cleaned the track pins. I will try cleaning the pins and apply a little dielectric grease. There are a lot of them. Sound like a good plan. Thanks.
