Running a head on a combo amp?

I was wondering if this would be possible. Ive got a peavey 210TX combo, and i recently baught a BAM head. I dont have a cabinet to use with the bam yet (im building an Omni10 right now) but i want to try out its moddeling effects and stuff. Is there a way to have my combo amp run the head as its power source?

Assuming that you are not asking if you can just run the output of one amp into the input of another (don't do that), just get a 1/4" coupling adaptor and add it to the speaker cable of the combo, and run a speaker cable from the output of the head to the adaptor. If combo has a closed back and no access to the speaker circuit, the no, you can't do it without opening it up. DO NOT plug the output of an amplifier into any input or output of another.
 
I have a Peavey T-Max 210 combo.

I also owned a BAM combo. There is no 1/4" speaker jack on the cab itself, so you have to get a 1/4" coupler (female to female). Then unplug the speaker cable from the combo head and plug it into the coupler. Then plug a speaker cable from the BAM head to the other end of the coupler.

Or, you can do what I did. Unscrew the 210TX combo's electronics plate (where all the connections for the crossover and wiring for the speakers and piezo are). Then cut the 1/4" male plug wires off and pull the wire out of the cab. Then get a female 1/4" jack and wire it up to the old 1/4" speaker connection (on the back side of the plate you took off) and mount the jack to the cab.

Now you can use it as a combo, or as just a cabinet easily. I cut the amphead section off my combo (and re-covered) and just use my T-Max head seperately now. The 210 is much lighter now without the head and the cabinet part that held the head. Plus I can use my T-Max head with anything else without dragging that ungodly heavy combo around.

You'll love the BAM. I owned the BAM 210 combo and in over all the 25+ years I've been playing, it's the only amp I've ever regretted getting rid of.
