It is possible to test the unit on a single supply, others have confirmed this in the threads, I have not tried myself however.
I am fairly sure you still have a PSU fault.
Capacitor problems cause just this symptom.
The ESR value falls when they go cold, and if left powered they can sometimes recover just enough, until powered off again.
If your PSU has not failed yet, then you can sure it will sooner or later.
I have 3 Radios, and every one has needed a PSU rebuild.
Does your unit actually have the warranty void sticker on it ?
I have to say that I am a little wary of you saying that your unit actually delivers the full 9.5V on load. Please dont even think I am calling you a liar, but the reason I say this, is because I have never in all the units I have checked (even the working ones) Seen the full 9.5V. 19 is usually spot on.
In an unrepaired working unit I have never seen much more than 8.5 ish.
Just thoughts of course.
