Extension cab for Peavey combo

I just bought a used Peavey TKO-80. It pumps 80 watts into an internal 8 ohm 15" speaker. I could connect another 8 ohm speaker cab to the combo to reduce the whole load to 4 ohms, and increase the power output. But would this damage the power stage of the amp? I haven't been able to find any info as to what the minimum impedance for this solid state amp is.

Anybody have any opinion as to whether this is a good or bad idea?

Peavey.com and go to the manuals section ... I looked quick, but all the references I saw were into 8 ohms ... the headphone jack is 4 ohm nominal, but the power/spkr output seems to be into 8 ohm nominal ... there also seems to be several versions of the TKO 80 and I didnt take the time to look at them all ...

The TKO manual in the Peavey archives does not show an external speaker jack on the back ... and again, most amps in the archives section have notes as to minimum impedance, and many also have minimum impedance written at the ext speaker jack ... this shows nothing for the TKO 80, and all figures are related to an 8 ohm load, so I would be very hesitant (especially if yours in fact does not have the external spkr jack)

The amp does not have an extension speaker jack, and I would have to install and wire one in. The documentation does not state a nominal or minimum impedance; however, all power rating information is given as into an 8 ohm load. That's all the information I have. I read somewhere on line that most solid state amplifiers can handle 4 ohm loads, but I don't want to find out that I own one of the few amps that can't.
