I bought a 5150 used on ebay for $400 and I'm pretty happy with it.
It just sounds really harsh and crackly. I don't know how to explain it.
I'm playing through a Peavey Windsor cab.

I'm just gonna re-tube it and see how it sounds.. so..
I need help on deciding what to load it with.
Thanks!

5150s are pretty agressive amps

You may want to spend some time tweaking your EQ's. Also if that cab has the stock speakers in it you may want to look into upgrading those. The windsor speakers arent the best to showcase what that amp can do.

you aint got no payschence. dis be a forum, not a chatroom, sonny boy.


harsh and crackly sounds perhaps like bad preamp tubes, but I'm not sure. look into JJs.

This x100

Your cab would make more of a rattling kinda sound if it's gone to hell.

Had JJ's in my 5150II until I got rid of it.

You don't have to replace the power tubes.

Really? Why wouldn't I have to replace the power tubes?
How many preamp tubes do i have to buy? and how much do u think it will cost total?

If it ain't broke, don't fix it. If you replace the preamp tubes and you're happy with the sound, then you just saved money. If you ain't happy, then replace the PoTbs as well. You don't have to replace one when you do the other.

Nope. They pop in and pop out.

Ahh ok. So you only need to bias an amp when you replace power tubes?
How much is it going to cost me for a full set of new JJ preamps?

50 bucks or so. Tubedepot.com

*stupid 09'er*

this space is for rent. PM me for rates

Ok, so I think I'm gonna just buy a full JJ set from Eurotubes.com

Do i just pop all of them in or what? Do i have to get the amp biased or anything?

Unless your 5150 is bias modded you just take the old tubes out and put the new ones in. Taking it to a tech is a waste of money unless you want to get the mod done.

I've had tube amps for a while now, but never actually had any go down on me

maybe you're not saying the right things? an amp likes to know you care.

Thanks guys. Oh and guess what.
I messaged the guy i bought the 5150 from and asked how old the tubes are..
He said AT LEAST 6-8 years old. Is that why I am getting such a crappy sound?

Tubes that are well, made and biased evreyyear, could indeed last up to 30 years, there are people who have been rocking the same tubes since the 80's. Its all about whether your a cheap skate. If you get evreything biased evreyyear properly, no probs then, and if you have decent tubes.
