Loud pop/screech when powering on amp

I have had cases where I bought used and device worked for a short time then developed issues. I would not be surprised that owners are inclined to sell at first sign of a problem before it has a chance to fully develop. You just never know buying used directly. Which is why it is always a good ideas to be sure to have some form of suitable recourse if a problem develops after buying used, especially for big ticket items. It may or may not be the case here. Just saying....

Another recent thread asked about "disciplined audiophiles" .  Being disciplined is always a good idea when buying big ticket items either new or used.

Thanks @larry5729 ​​​​@mapman. I just reached out to the guy I bought it from (bought it here). He was really great so I’d like to believe he’s better than that and didn’t try to offload it…I’ll see if he responds. It’s my second system and I paid under 1K, so though that’s a lot of money, it’s not the end of the world. And I can always fall back on the Outlaw 550 for just over $800 with shipping🤷🏼‍♂️.

Waiting to hear back from AR (emailed and called but was on hold for 20+minutes with interludes of music and a recorder woman’s voice speaking French🤦🏼‍♂️🔫😂)

Outlaw 5000 should have said😁

How old is the amp if > 10 years could by leaky capacitor 

Cap blew. Unplug, open up, and look for bulging cap.
