Hi friends. Problem solved.

I can't say why or how. After a lot of trial and error changes I decided to take voltage readings again. First thing I noticed was that R13 was blackened. I changed it and started taking the readings. Voltages around V4 (EF80) didn't seem right, so I changed it. I eliminated the decoder to make sure I had signals coming in right, then connected the decoder and this time I was getting a clear sound and could adjust the LED. From then on things got a lot easier and it's playing right now.

So, thanks a lot to both of you because you gave me the courage to keep on trying until the end. Besides, it was a very worthwhile learning experience as I had never worked on tuners before.

Warm regards and best wishes,
Joe A
