Peavey 240 Standard: oh, so many questions

My first gear post, and it is involved.

My grandfather was a bassist in country bands since the mid-60s.

He died in 2008 and I inherited his rig, bass and a quite nice RCA mic. I was playing (forced, [like my grandfather i take the gigs where i can get them]) guitar at the time with a tube amp so the solid state sat.

So this amplifier a Peavey 240 Standard in very goid condition. The power chord was beat up, looked like a mouse chewed through it, but that was the only thing I had to do to it to get the thing powered up.

It sounds great, warm with a little grit to it. Real fat and moves air. Until I cracked it open a little too far. Then I entered Buzz City, population Me.

The speaker in all its paper cone glory is failing. So I wanted to replace it with something like was in it, snd slowly tearing itself apart.

So I looked it up and there a glut of double talk. And Peavey has manuals in .pdf format for the 260 Standard, but not the 240. Twenty numbers less makes it less cool, or something.

I read it's a 150W Eminance at 8 ohms. But the amp is 4 ohm. Then I read the speaker is a 4 ohm marked as an 8 ohm. Or that it's a Fender speaker, a Black Widdow, or an EV with RMS from 150 to 350 watts.

I shot an email off to Meridian, Mississippi and I'm awaiting an answer.

Also, from some things I've read the head 120 watts per channel at 4 ohms, and can be bridged using a chord as jumper.

I've never heard of an amplifier that has two channels, running independently.

I am obviously lacking in this early 70s solid state voodoo.

So how does one bridge the channels without destroying the head? And any options on speakers that can be used on the one channel and wont blow out in bridged mode would be much appreciated.

Thanks in advance for reading this.

Wish I could help, but all I'll say is this - that era of Peavey amps has an incredibly loyal following. They must have done something right! I hear nothing but good things. Enjoy the amp, and enjoy the ride figuring it all out!
Thanks much. My grandfather took good care of it. Near mint. And it does sound good. I'll probably take the Meyer to the speaker on the ohms but I'm still blown away this bridging channels business

It has a great early 80s hard-core punk sound to it. With my cheapo Dan Armstrong I look forward to making some sound with it. When I figure it all out and my band records I'll post links to the songs.

First, the speaker would have almost certainly a Peavey (probably by Eminence) during that era of cabinet. I am almost certain that it was only offered as a head and not a combo (with speaker), so the cabinets you are looking at may not have been from that time or originally matched with that head. It would not have been either a Fender or EV speaker from Peavey. It might have been a BW but from a later cabinet.

It's rated at 130 watts into 4 ohms, 85 watts into 8 ohms. Will work fine with either load. You will be better off with an 8 ohm cabinet if it's a single driver.

Even though some may be rated to drive 2 ohms, I don't recommend that.

Hey, thanks for the response!

I have the 240 head, but I looked at the manual for the 260 you sent and I'll read it in more in depth in a few.

So, the concept of the 240 is the same as the 260? Each channel being 120 @4 ohms if I gather right, and 240 bridged. Though I'm not sure at 8 ohm.

I have the single 15 cab that my grandfather bought at the time with the original s pear in it.

I'll probably have to push at at 4 ohm as my guitarist is quite loud.

Meyer has nothing to do with it all. New phone and my AI has a real 'tude on it.

(My amp is at the practice pad, but this is exactly the same)

The Standard is a guitar amp, in case you hadn’t already noticed. The equivalent bass amp was just called Bass (doh). From that photo it’s from the same period as the Festival amps (early 70s).

I've never heard of an amplifier that has two channels, running independently.

It has two preamp channels, which was quite common on amps for decades. The trick of driving the instrument through both preamp channels using a jumper is what you were reading about.

the two channels being referred to are the preamp channels
As @agedhorse said, you aren't combining the OUTPUT channels (since this amp only has one output channel).
There are probably multiple speaker outs - but they just give you the option to drive multiple cabinets from that single power amp output.

Folks talking about "bridging" this amp are using the term incorrectly.
"Jumpering" would be a more accurate way to describe using both PREAMP channels at the same time.

To do that, run a patch cord (jumper) from the secondary input on one channel to the main input on the other:

In this example, you would plug your bass into the bright channel's "Hi" input, and the patch cable would carry your input signal to the "Hi" input of the "Normal" channel.

Lots of amps in the late 60s & early 70s were like this - later Ampeg B-15N and the Acoustic 150, for example.

My favorite way to use this feature is to set up the "Normal" channel to sound fat and round, then blend in just enough of the "Bright" channel to add clarity.

The speaker probably wasn't matched to the cabinet as scientifically as well-designed speakers are today - so any 15" replacement speaker appropriate for bass guitar should sound at least as good as the original one did.

If you want to go the extra mile, measure the internal dimensions of the cabinet, and any ports.
With that data, you could probably select a speaker that takes the cabinet's performance up a notch or two.

I found the literature online (finally).and I think we might just all be right. Seems it functions as guitar, bass, and PA head. Talked to the most local authorized tech I could find and he confirmed that.

The jumper is interesting.
 
It’s a guitar amp, makes a pretty piss-poor bass amp and I’ve never seen one used as a pa.
Please don't misunderstand me. I'm no expert. Just saying whst the tech told me, and what I read online.

To my ear it sounds pretty good. Its not Ampeg or Eden of course, but i wasn't expecting either.

Here was the info I found on it..

He probably was describing that like many Peavey amps of the 70s and 80s, the 240 series power stage was used in guitar, bass and PA head versions.
Correct, the 130W power amp (260 module) module was used in a variety of products, this one is a guitar amp. There were several distinct versions depending on the year. This module was the first (or one of the first) multi-purpose power amp modules designed by Jack Sondermeyer, intended to be used in multiple products. Jack came to Peavey from the semiconductor industry, he was a solid state power amplifier applications engineer at RCA, and Peavey made Jack an offer that he couldn't refuse in the very late 60's and by 1770 or so he had moved to Peavey as the head engineer. He held that pose for decades.

Because the Standard had reverb, it was really a guitar amp. Sure it could be used for bass, wouldn't have sounded very good but would make some noise.

Well...in so far as what sounds "good" is at least a little subjective...

What I mean is that lots of folks use old Peavey solid state guitar heads for bass, but they tend to be punk/metal/etc bands that value gross, loud tones over what is usually meant by a "good" bass tone. OP mentioned that he got a great "hardcore punk" tone out of it, and that's about what I would expect.

Personally, I love the old Peavey tone that sounds like it comes with a leather jacket, skin tight jeans and permanent sneer.
