Oh yeah, why didn't I think to bridge the Delay instead of remove ..lol.. thanks that's an easy trouble-shooting.

Already swapped all the tubes from working channel but still the same.

Sorry, didn't mean to hijack your thread but it's very helpful in my case. I will start with C103 to see what happen.

R114 and R115 value pretty much the same.

What happens if you disconnect R114? Maybe C103 is shorted and R114 has failed short the first time.

I think I will start with C103 since I removed both R114 and R115 to do a measurement, the R114 has exactly value while the R115 value just a little slower than the R114 but not that much.

I haven't done removing R114 to power on yet. I will do that too. Actually, I don't have time to fix it right now since working to remodel the audio room. May take another 2 months to complete before I can setup and have time to work on it. Your info and others are great guide to start trouble-shooting. All I did was swapped the tubes, compared all the points from working channel, and replaced the R115. Haven't done anything you and others mentioned in here yet.
