Reciever makes whooshing noise when powered on and off

Ok, higher voltage it is. Seems to be lots available if I turn to that auction site.

I have a simpler suggestion. Before you shut down, switch the speaker switch to off. When you start up, leave the switch off for 8 or 10 seconds after startup, then turn them on.

Doesn't really fix the fact the caps are garbage and are turning into big resistors.

If you like counterfeit parts that aren't what they're supposed to be.

Better late than never, right ?
So yesterday I finally got around to replacing the output caps on the r3000.
And behold: the waterfall in the speaker on turning on/off is gone!
Thanks guys for good advice!

Nice. You can bet your booties those weren't the only caps on their way out though.

Yeah I know. But just wanted to replace these two ruling out other nasty stuff like unobtanium powertransistors and such. Now I think I´ll go for the full monty on a recap

One word of advice, don't get your capacitors of FleaBay, or use any cheapo off brands. I tried some of the cheapos on some inexpensive gear of my own. The results were less than desirable and ended up yanking them.
