So today i bought a brand new Peavey 6505 plus at guitar center, brought it home and hooked it into my mesa boogie 4x12 and it sounds like absolute crap! I messed with settings made sure it was plugged into 8ohm ect ect and i cant find the problem. there is a loud hum that overpowers the guitar and its definitely not usual at all.

if anyone has any insight please help me out!

Take it back. This sounds like a transformer issue, which is definitely not something you want to mess with on a new amp.

Check to make sure all the tubes are seated properly in their sockets. Wiggle them gently and push down.

did it sound like that when u tried it out at gc? possibly something wrong with the speakers?


I played it at low volume and it didnt sound anything like that until i cranked it up.

Have you ever smelt a circuit short? it smells really acidic, have a smell of the back of the amp, if you can smell a metallic acidic smell, good chance your transformer has fused...

Other than that. It'll be a failed resistor, 50c piece that a tech will charge you an hours labor to replace, just take it back if it's anything other than the loose tube that was described in the quote.

Listen to Colin. He knows what he's talking about when it comes to stuff like this.

And it sounds like you just got a dud TS. I've only played one Peavey that just flat didn't work when it was brand new and I've played a lot.

so i just took open up the back of the 6505+ to make sure the tubes were in there place and i was looking around and noticed there were no preamp tubes??? i took out the four power to make sure they werent hiding behind them and they are no where to be found. there is one box to the left and one to the right (yes i know nothing about tube amps) theres no way they could be in there right?

if not how could guitar center get away with selling me a modded amp with no preamp tube slots??

make that +3.

also, onc you get it replaced/sorted out, try running it at 16ohm, both head and cab... depending on what mesa cab it is. i know some are 8 ohm only. if that's yours, nevermind.

one last thing, it's a high gain amp (one of the highest, actually). expect to need a noise gate. you described this sound as unusual, but even if you get a new one that's perfect shiny and new, when you open it up you'll hear noise. if that noise is oscillating, get a hum-x or power conditioner that will eliminate 60sch.

what kind of power conditioner do you recommend, right now im looking into buying an ns-2 or decimator (i have to try them out side by side) but i also was researching power conditioners and bbe sonic reducers. any insight?>

I thought a power conditioner protected your gear from surges and spikes and whatnot. I didn't think they eliminated noise caused bye electrical signals.

I may be wrong though

So, can I use this thread as argument in the next Bugera vs used Peavey thread?

I meant specifically one that does that. My monster3500 handles it, though I can't think of any other models off the top of my head that do... haven't used a furman in ages, but i don't remember it cancelling 60sch, and i like to think i would remember.

It will definitely fix noise caused by bad grounding. It will make sure everything is running at proper, constant, levels so that no hum is produced.

The preamp tubes should be in the lower right hand corner, you have to unscrew the plate to access them. Confused the hell outta me back when I had one as well.

Anyway, just go get a new one, you shouldnt have to pay anything or take it to a tech if it's brand new.
