The tech pointed to his bench and there were SIX other 606's he was working on for the same problem! This is a problem with the 606 and apparently not the other models in the line. Mine was under warranty and I had my receipt, so it cost me nothing.
You have either been given some incorrect info or relayed that info inaccurately. The 100uf's both original and replacement are 4 volt and the add on caps whether .1uf or 1 uf are both 50 volt. And the power supply isn't underrated but simply becomes unstable without enough cap to keep the regulators from oscillating. It was an engineering/design error and is correctable by the bulletin.
And that very same board is in 1 other onkyo model and one other integra model. Not just the 606.
And a similar problem has cropped up in a next gen model. BEFORE they figured out the problem with the 3 models from teh previous year. I doubt onkyo will have this problem again for a while... Lesson learned i imagine.
And yes. I know I'm overly simply stating the problem.

No biggie. I've noticed a lot of shops are terrible with accuracy or honesty.
/me hates that :~(
I've run out to the customer area of our shop occasionally to correct my manager in relaying the facts in a repair more than a few times

BTW... At the peak of this situation I had nearly 2 dozen U41 hdmi pcb situations sitting on my shelf at the same time :-/
I think the situation is 'in hand' now by onkyo. It was a bit of a runaway situation a while ago. But I can quote situations by nearly every major manufacture in the last 10 years that mirror this so don't be to judgmental.
