    Hi folks and thx for reading this. I purchased an open box, mint condition miniMega 1000w amp for use with my PVH 210 cabinet. After a minute or so after turning the amp on the fan kicks on (at different speeds sometimes) and speaker outputs shut off so no sound coming through. Headphone jack still works but at lower volume. I read that these heads have issues with overheating and I'm hoping there is something I can do to fix it myself. Peavey isn't taking returns/repairs at the moment and can't find anyone local to look at it. Any help is much appreciate, thx.

    What part of the world do you reside in. Filling in your profile fully helps us to help you.

    How much electronics servicing have you done and what test equipment do you own?

    What is the impedance of your speaker cabinet and has it been messed with?

    First, the assumption of overheating may very well be incorrect. A QUALIFIED tech will correctly diagnose the cause of the fault before assuming the source of the problem. Otherwise, it would be very difficult to successfully and economically repair an incorrectly diagnosed (or guessed, or assumed) cause.

    Thank you BassmanPaul, I updated my profile. I do not have much servicing experience but I own a multimeter and know how to use it. Amp is 4ohms, speaker cab is 8 ohms and in new condition. Working well with my backup Bugera 5500 amp. Not hearing back from Peavey with phone call messages or emails so looking like I'm on my own. One guy told me it may be a protection circuit not working or maybe a short somewhere but that's all I have to go with so far.

    Thank you agedhorse, I haven't been able to speak with a qualified technician although I have left multiple messages at Peavey. I've asked questions here given the info I have because I want to get my amp running somehow and have no one near me that works on them.

    Well if a 8ohm 210 makes a 1000 watt amp overheat. It's garbage.

    Also unlikely.
    Probably another problem with the amp

    If another amp is running the speaker cab just fine without issue. Assume it's not a cab issue

    Another issue which we see often is a speaker cable issue.
    Is it the same cable your testing both amps with.

    Speakon connections love these problems.

    Just for interest measure the DC resistance of your speaker cabinet. Did you buy the cabinet new or used. Trying to ascertain if the cabinet could have been rewired to 2Ω to get every last watt out of an amp.

  9. I own one of the same. When I had a problem, I sent it to Peavey it was serviced and sent back within a couple of weeks and it was not expensive. IIRC it was about $60-$70. I can tell you they were, and possibly still are, working with somewhat of a skeleton crew for the last few months. When you get ahold Of them they’re just going to tell you to pack it up and send it in. I would suggest using the box it came in since you’re not gonna find anything better or smaller. It’s on your dime going there. I have used a MM1000 a lot, in the last couple of years. Although I used Agedhorses’ Genz SM12 this afternoon. They can’t fix it on the phone. When you box it up include, your name and address and phone#, a description of the issue, the serial#, best time to call. They’ve been good to me and this is the first piece of Peavey gear I’ve owned since the 80’s. For me, having an amp failure isn’t the end of the world. But the company’s response and resolution of the problem has made a fan of both the amp and them again. I think this a pretty darn good sounding amp that packs a wollop!

    Peavey is running extremely short-staffed right now with several people working from home. They are running behind on literally thousands of emails and trying to get caught up. You must be patient with the pandemic as Peavey was shut down for months and are just starting to get back up rolling. I believe their repair service is actually down to only two techs. You might have better luck taking it to a service center; agedhorse gave you quite a list to choose from.

    I have two Minimega heads, I run them hard (sometimes into constant DDT compression) and they don't break a sweat into 4 ohms. I run them hard like an old Peavey. That's actually why I chose Peavey when I went Class D, because I used to run my old Mark III head into constant DDT power amp compression and actually preferred the sound it made that way. It never shut down or gave me one problem in the last 42 years and it has required no service since new.

    My advice..since you just bought it...return it for a refund. You shouldn't have to repair an amp you just bought, and there's not really any repairs you can do on those amps yourself.

    When it shuts down is the fan still running? I had a similar issue with my MiniMega.

    Thanks, definitely an amp problem. Fan starts up and runs unevenly with or without cables plugged in. I'm using brand new Speakon cables but tried 3' patch cord (which works with my backup amp Bugera 5500).

    Thanks, I'll check it. Bought it from friend who bought 2 new and never used this one it so I know the wiring is factory.

    Thanks Kirk. I did speak with a secretary about a month ago and she confirmed they were very short handed and not accepting mail-ins for repairs at that time. She then forwarded me over to Roger who is a tech guy there so I left a message but I haven't heard back yet. Hoping he will tell me to send it in.

    Still the box and all contents....mint condition other than this issue. I bought it from a music store online and by the time I started using it it was too late to return.

    Thanks, I'll have to call again to see if they can squeeze me in yet. I'm a big Peavey fan and play small/medium size venues so this amp with my PVH 210 should be perfect. It's driving me nuts that I can't use it!

    Thanks. Can't return because I waited too long to use it enough for this problem to arise. I plugged it in real quick when I bought it, heard sound come out, then shut it off. Last couple months I've only used headphones and that port is fine, I just thought the fan thing was normal. When I recently plugged in the cab I realized that when the fan comes on the cab outputs shut off and it's too late to return.

    Thanks and no, the fan shuts off a second or 2 after power is turned off. When it's running the fan is unsteady, not one smooth speed. What happened with yours?

    Again, at this point in time, you are going to have better luck going through an authorized service center. Peavey is backed-up and short-staffed like you would not believe due to the pandemic.

    I know several people there, and I am giving you the best advice I can give. Please check with one of the service centers listed on this thread.
