Is my amp dead for good?

[packrat]

Definitely, I’ve seen 220/240v plugs jump up when a Diesel, or natural gas generator motor goes into overspeed. But a whole grid. That’s almost 2x’s the nominal voltage.

It's also suspiciously close to what you get across a couple of phases.

That does look like a SMPS flyback design. The chip mounted vertically with the black heatsink is probably an integrated PWM controller/Power MOSFET component.

That may have given up the magic smoke within as well. Hard to tell in the blurry photo but it appears to be a TO-220 package. This will be easy to replace rather than surface mount packages.

Yeah anything over 250 between phases is considered high voltage in the USA. That’s usually when things go
pop!

Note that many techs will not work on failed repair attempts by end users or other unqualified technicians.

My own shop policy follows this because there's no way to know what damage was caused by the original fault and what is damaged by the repair attempts.

This is a good policy; when someone else has been into it, it becomes very hard to troubleshoot the initial problem because the guy that was working on it before usually destroys valuable evidence and potentially introduces new problems.

 

[Spidey2112]

Any idea what parts would be affected by this? The internals of the amp look perfect, there is nothing visibly melted, burned or otherwise suspicious?

Tell me you have at least tried a different outlet... no sarcasm, believe me, but was power restored?

(I'm now into changing "or" or "er" suffixes into "ador" just sounds badassed)

Matador ---> Matadador

hahahahaha!

At work, I've been given the nickname, 'Hoover' as I usually end up cleaning up the problems, after the tech's before me... believe me, it sucks...

 

[BadExample]

I’m not aware of anywhere with a functioning court system that takes this approach. Historically, marginalization of the rich is a non-observed fantasy.

Uhhhh, try this: Face North, look over your shoulder, see the boarder? There's an example.

Court? You can't afford the legal system. It never goes to court.

I'm not going to list them out here & risk offending someone from one of those countries, but OTOH they'd probably confirm that I'm right
Expats get discriminated against often, it's just a fact of life some places.

Most people in the US live a very sheltered life.

At least you can go shake them down for info over what they did before it was passed to your hands.

I'm not in the US this week, so that example won't work as well as you think. A trivial search suggests that corruption is rife with both money and political influence in the courts that I think you're talking about and that means the system is strongly biased in favour of the rich, not against them.

Which was the point I was actually making all along.

The kenyan power grid is 240 volt/50Hz if all goes normal.
You can file a claim for damages against the provider but after living here for 14 years I have yet to meet or hear from any private person ever receiving compensation for damage caused by their faulty grid, I got better things to do.
And suing a company who's majority shareholder is the Kenyan government.....

Yes, I tried the amp on different sockets in different locations to be sure.

Good policy!

I'm an occasional tech for a mom and pop music store, what their guitar tech cannot fix he passes on to me - aaaaggghhh.

First I have to find and correct the faults he has introduced (his abysmal soldering is the worst I have ever seen*) before I can fix the original fault.

I know he means well but I just wish he would keep out, it would be far easier for me and cheaper for the owner/customer. Luckily they sell way more guitars than amps and pedals so I don't get called upon very often.

*That includes mentoring apprentices for about 20 years and some of those had difficulty working out which end of the iron to hold!

Passing ships in the night... usually, it's the shift(s) before us... believe me, I would like to shake them down, not necessarily for info, either... .

When the phone rings, a qualified tech rarely answers the soldering iron...

Hoover says: "It sucks."

Well at least they didn't give you that name for the way you dress.
"Not that there's anything wrong with that!"

does home/renter's insurance cover the fried lighting & appliances?

Check your policy
It's right after "Swallowed by a shark", but before "Meteor strike"

beans-on-toast, that was spot on! I bent it over and found this:

Is there anything else I should be looking for?

I've got a lot to say about this, but this isn't really the place. The OP has already stated that he doesn't expect to be compensated.
<comment about "favour the rich" removed for the sake of avoiding politics>

 

[agedhorse]

I think the political aspect of this whole discussion can be summed up non-politically as "the system always tends to favor those who are in power over those who are not", and has for thousands of years. Those who are in power tend to also be the ones who have a history of converting power into control and wealth.
