Thanks Stan,

Yes, T401 is good and good tin on all leads.
?
I did a careful check around L401 and the associated capacitors C401-C404. Everything looks good there and all resistance/continuity checks of L401 are good. Again, looks like all leads are clear of enamel. I scrape off the enamel prior to soldering on all toroids.
?
What I am looking for is any other tests I can run either voltage, resistance or signal flow checks with a scope, etc. to help narrow this down.?

As for the PCM1804, I think things are better than they were with the previous one. With the original in, about half the time there would be no audio on power-up and the other half would be a loud noise, now it is just loud noise and the S-Meter to match it. I suppose this one could be bad as well but would like to know of some ways to validate whether it is good or bad by doing some checks.
?
thanks,
Bob
