Peavey 6505+ Q

Hello everyone, I hope someone can offer some advice. I recently bought a used peavey 6505+112 combo from guitar center. I had to get it online so i couldnt test in store. So I opened it, plugged in the guitar turned the amp on and... nothing.

No sound at all coming from the amp. This is my first real tube amp so i dont know if im stupid and overlooking something or what. The tubes in the back glow a little bit orange, the green light comes on in the front but no sound at all. The peavey logo lit up for half a second then went off but the green lights stay on.


I plan to return it in a few days but i dont want to show up and it be something trivial and make myself look dumb which i pretty much am lol, not to mention its a very long drive so id appreciate any advice. Thank you to anyone that can reply.

is the speaker plugged in the back?
Are you turning the pre and post gain up?

Plug your guitar into the fx loop return while the amp is on. do you hear anything?

Take it back

I guess you waited long enough but tube amp takes a little while before you can hear anything. Like 30 seconds or so. Then, make sure all volumes are high enough. (Guitar volume, volume on amp, master volume). If there's a gain knob, make sure it's not at 0.

You probably already did all of that stuff anyway, maybe try another cable? Another amp? Another Guitar? Another pickup? Remove anything in between the guitar and the amp like pedals.

If it still dosen't work I guess there's something wrong...

Hope you'll make it work!

You turn the power on and wait about 60 seconds, then turn on the standby switch... Then you should hear it with the volume up some.

Is it connected to the speakers?

Do you see anything plugged into the speaker out section on the rear of the amp?

Is the standby off...?

'Post' is your volume control for both channels, if you had them turned up to 10 trying to get it to work you may have actually blown something up, If not then perhaps the speaker is unplugged...but I don't think running the amp with no speaker plugged in is good for it either; It may be best to take it back, in case you mess it up worse.

The Peavey logo light is supposed to stay on for as long as the amp is on.

Also while it's a good idea to let the tubes warm up in standby it doesn't take 30 seconds for them to make sound :\

This sounds like the speaker cable came unplugged in shipping or something.

Do you see your speaker outputs on the amps back panel?

Can you post pictures?

And don't turn your amp on for the time being.

Yeah, the loose cable you saw should be the speaker cable (just check where it comes from), plug that in the speaker output and while you're at it check if the Impedance switch is set on 16 Ohm (assuming it still has the stock speaker/other 16 Ohm speaker).

+9000

Having no load (=Speaker) connected can cause serious damage to your amp!

So- let's gets this straight- you have nothing connected to your speaker output next (directly to the right of your FX loop) and you have a loose cable- if it is coming from the speaker box section plug this into your speaker output- shouldn't matter which one as they are wired in parallel. Set your impedance to 16ohms and turn it on and play.

Guitar center may have disconnected it for shipping purposes in case it got impacted there.
