Fred, I did call Lionel from my workplace while on my lunch break today. There was almost no waiting-on-hold time at all. I got a verbal return authorization number, to be followed with a mailing label emailed to me. I will send the Legacy base to Lionel for repair.
John, I will use Dale's signal strength test rig before I send the Legacy base to Lionel for repair, to confirm that there is no 455KHz output. I will use my working TMCC base to test the signal strength meter. I will have to go purchase the needed parts to build the test rig.
Progress! Thank you All......Paul
