Okay gang, I've had my Archon since the end of the summer, bought new, and today, it suddenly decided it didn't want to power on. I checked the circuit breaker for my house, and that wasn't the issue. I also tried the amp on a couple other outlets to no avail. I tried other amps on the same outlet and on other outlets in my house and they're fine. Has anyone else had their amp die suddenly like this? I just sent a ticket into PRS, but anticipate not hearing back from them for a couple of days. Anyone have any thoughts as to what could have caused this? Blown fuse? Bad output transformer? Bad board?
 
There it is...the response that's about as helpful as a turd flavored lollipop. Clearly didn't read the OP outlining that there is a ticket open.
Here's another turd flavored lollipop for ya:

Nobody sits and memorizes the original posts, so if KBC didn't see the thing about the service ticket that's OK.

Any idea what a possible cause could be is a wild guess. You know this, of course, and you're merely frustrated. That's understandable. But the advice to call the dealer and get them involved was good advice.
 
Considering this was ordered online from a retailer over the summer, I doubt that they'll be much help. There are no dealers in my immediate area. I'm stuck dealing with PRS directly. WAS hoping to see if anyone has encountered this and what the fix was.

Check the fuse, probe it for continuity ideally, and I will walk you through it.

It's probably shorted PA tubes, taking the fuse down.

If it was Sweetwater, chances are they'd help. I don't know about the other online vendors, but maybe it's worth asking.

If not, you know who not to buy from again!

Northeast Music (Jack Gretz) takes great care of me, and I've bought online only from him for 24 years.

He's gotten very fast responses from PRS. I've only had a couple of problems to deal with over the years - the old poly stuff tended to be brittle along the edge of the fretboards and flake - but he had PRS send a return UPS pickup label straight to the factory within a day each time, and I got my guitars back within a couple of weeks.
 
It's probably a capacitor or a switching transitistor. Those seem to be the culprit in most amp failures.

Changing out the fuse is just likely to net you another blown fuse. They blow because something bad happened.

It could have been a power surge, in which case you are in luck and that new fuse won't just blow (unless there's another one), but you are still taking the risk of the price of a fuse. It's at least checking.

DO NOT put a larger value fuse in, you risk causing more expensive damage.

Really? How???

It's like sneezing and blaming cancer. Different symptoms.

OP: test the fuse. Then test each combination of two PA tubes lugs for continuity. If the lugs are shorted, this is your problem. You can do it quicker by replacing the fuse and turning the amp on with no output tubes in. Just keep it powered for very short time, and dont forget the speaker load. If its powering in, this is your issue. Replace the tubes and you back in the game.
 
Why not send it to PRS? Might as well use the warranty!
Yeah, that would work too. But IMO not knowing the basic troubleshooting techniques in a tube amp is like not knowing basic maintenance of a classic car. Im toying with an idea to make a thread just for that. Nothing invasive; just poking and probing

Like if I have a time for that. Im two weeks delayed to answer to a PM to you, Les
 
My HXDA had a similar issue. Fuses blew but there was indeed a capacitor issue. Motor City Guitar amp guy fixed it with input from PRS HQ guys. That Gretz guy got Les that awesome DGT, but the Motor City guys are first rate too.
 
Well, I'm still waiting on a response from PRS. In talking the issue through with a somewhat local amp repair shop, they suspect it to be a bad capacitor. I don't really want to have them dive into the amp and me wind up eating the cost of repair if this is something that would likely be covered under warranty. I'm just super bummed out that the amp's relatively new and already died on me.

Motor City is indeed a great shop, it reminds me of Meyers Music as it was back in the day - huge, great selection of kiiller gear with everything out on the floor.

But Motor City has even more stuff, much of it high end.

I've bought every guitar and amp I've owned from Jack since 2001, with the exception of the Two-Rocks. But I've gotten lots of other gear from Motor City.

Bum deal that your amp quit on you; I’d be disappointed also. As other have mentioned, depending on who you purchased the amp from, some dealers can be very helpful in getting your issues sorted out. You really should give them a call… never know until you ask, right?

PRS will get with you on it. Rest assured they want you to be happy with the amp. I had an issue with a small part on a new guitar, and they had me send it back to them (on their dime) rather than make me dive into it. I anticipate they’ll walk you through the user-based troubleshooting, and have you either send it to them or the retailer if needed.

Beyond fuses, there’s a lot of things ranging from simple to complicated that can make any electronic device become uncooperative with doing what’s expected. If you’ve checked the fuse with a multimeter or other fuse and it’s good, tubes would be next for me if you have power showing on the amp. If no power is showing, I’d say you’re into experienced amp diagnostics… the dealer, PRS, or a local guy (the latter might be on you).

I’ve never had an Archon, and have never had anything other than non-tube amps shut down on me as you explain it. Sorry I can’t help with that. You mentioned having other amps so, on the positive side, at least you have something to make noise with while you’re waiting!

I understand the bummed part, but PRS doesn't use junk parts and at some point, we all have to understand that even good parts CAN fail early. Doesn't happen often, but they can.

Hope they get it sorted quickly for you.
