Nice diagnostic work! That's a horrible design to work on, with all the components buried underneath. Would have liked to see your work R&Ring the transistors. I like to watch the technique of others who are skilled at what they're doing. Did you replace all four, or just the offending pair?
Hi Chas, I thought that I would never see a RUclipsr use what I was taught in the early days (heat and freeze spray). I still use that technique!

Yes, being an "Old Skool" engineer, using the wife's Hairdryer was always a problem, she kept wanting it back!!! Freezer is such a handy tool.
I have the same right channel distortion
I will drop your knowledge in my guru
Thank you for this
I thought I was losing my mind chasing this down .
Thanks and welcome
Another good fix Chas! Hope the wife is feeling better! Cheers!
About the same for someone her age. Thanks for the thoughts.

Getting good views of the testing of the transistors was difficult so I cut that out of the video.
I just replaced just the offending pair.
Tuner amplifier , so a receiver?
Yeah, you could call it that, the customer mainly used it as an amp.
