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.
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!
