Also, two outputs labeled 8 ohms is pretty much a dead giveaway that it's a minimal 4 ohm impedance. Two 8 ohm cabinets equals a 4 ohm impedance to the amplifier. -Luke

NOPE NOPE NOPE !!!!!!!!!!!!!!!!!!!!!!
The outputs are labeled 8 OHM Which means each out must be no lower than 8 ohms.
The internal crossover splits the signal so you can run a 10" cab Ch A and 15/18 cab on Ch B with the proper freqs going to appropriate cab.
But you can NOT run a 4 ohm load on either output.

Good Lord. It's two output jacks in parallel, one amp, rated 250W RMS with a 4 ohm load. You can plug in any combination that adds up to 4 ohms or more.
I have the exact same amp but I blew up the preamp the other day plugging a lead in the wrong socket at the back.
The quoted RMS must be at some very low level of distortion. It slays my 300W power amp which I have verified puts out 300w at the onset of clipping.
Peak watts is a non-spec in any amp. Even RMS is a bit shaky. Rest assured 250 trace watts is the boomfyest 250W you will ever hear.

Hey Schlyder, you have a pdf of the schematic by any chance? I found one but it's missing the power supply schematic.
And you want to join Team TE? Take # 181 member if you like.

I'm talking about a total minimum load for both parallel outputs at the same time. -Luke
you are talking about VS's amp here, yes? ... Because I know 8 ohm is the lowest for each out on my amp. But there are two 8 ohm outputs on mine.... can they both have an 8 ohm cab in them running an overall 4 ohm load. The amp says nowhere if it will safely run on 4 ohm load.
It's just Trace Elliot way of doing things. The 8 ohm jacks are wired parallel. Quid pro quo two 8 ohm cabs is a 4 ohm load. I guess they assume too much. It is all in the manual that coame with the amp.
If you bought a 4 ohm cab the manual with it would tell you to only plug one of them per channel into a trace amp. There are only a few 4 ohm trace cabs.

AFAIK, it is perfectly safe to run "1" 4 ohm cabinet into the amp. Definately not two of them though. -Luke
"For example, for an amplifier rated at 4 ohms minimum safe load you could run it with one 8 ohm cabinet, two 8 ohm cabinets (for a net load of 4 ohms), or one 4 ohm cabinet."

Didn't get the manual with the amp...
I just have one downloaded from the interwebs. And it doesn't say what the "Min Ohm Load" is.
So I am correct then in assuming it is
safe to run... 2 - 8 ohm cabs @ 4 ohms or 1 - 4 ohm cab @ 4 ohms.
I just don't know why it's not labeled on the back??
For the same reasons the effects loop jacks and the DI out is in the front...?...
One could argue that in 1996 nobody owning a 4 ohm, 500W peak capable bass cabinet needed telling not to plug two of them into an amp that said ok to plug in but two 8 ohm cabs. Between the instructions on their cab input panels, and the amp instruction manuals, they have every other angle covered .
Correct. If you use BOTH outputs, the cabs must be AT LEAST 8 ohm or higher.
I've read the manual and it looks like you can go to 4 ohms on ONE output only...
That said ... your specific model is NOT included in the list of models this manual covers.
It covers from AH300 and up.
I have not been able to find a manual for the 130, 150, 200 or 250 watt models.... in years.
In the "Better Safe Than Sorry" category...
I would not run a 4 ohm cab in an 8 ohm output until I got confirmation from Gibson/TE Tech Support (don't call Peavey - call Gibson TS),
A qualified tech that can LOOK at the amp and tell,
read a manual for THAT model, etc.
Now there is the possibility that someone ran two 4 ohm cabs in it already...
I forget ... how long did you play through it before you bought it?

Relax man, it's all good at 4 ohm. I've got the same amp open on my kitchen table. Parallel output jacks.
that's what I needed to know. And you said you have run it at 4 ohms. Yes?
DUW- here is the only manual I have.

It was made in 01/'96. I purchased it used in 1998 from a music shop in Victoria, BC. No idea hour many hours on it, or how hard it was worked prior to my owning it.
It was minty new looking... came with a T.E. cover for the head, and rack ears. And was priced very good. I played through it a few times, maybe two hours total before I bought it. I didn't wait too long before pulling the trigger. TFDS
Turns out the GP7 Series 6 preamp I bought is actually a AH100 bass head. Do the TE amp heads have to have a speaker load attached or can I just use the preamp alone?
It's solid state, doesn't give a rat's () about idling with no load. Has it got "preamp out" or "line out" on it though? You might have to get a tech to tap into it. Not a big job methinks.
You didn't say what you were using it for, maybe get away with the DI? I'm pretty sure they all come with those.
