I don't have a cab right now, but I do have my Mesa F-50 combo (1x12), can I use that amp as a "cab" ?? and HOW TO do it?

I play an Einstein and I own a Marshall 6101 Combo with a Celstion Gold Speaker (100 W). Sometimes on rehearsals, when I don't want to carry a bigger cabinet, I put the Einstein on top of the combo and plug the speaker cable of the Marshall-Combo into the speaker out of the Einstein. It works perfect. But you have to match the impedance, of course. Though - the Einstein sounds better with my bigger cabinet.
Greetings

If the cable is too short, find a lamp cord or an old extension cord, cut the speaker cable, and splice in the extra length of lamp cord, making sure that you do not reverse the polarity in the process. Insulate the spices with electricians tape, Wire nuts, or crimp connectors to prevent shorting. It may look ugly, but it will be functional provided that you kept the polarity correct when you wired in the splice. --You can do this by marking one side of the splice w/ a sharpie or other permanent marker, and wiring it up according to the mark.
It's cheap, it's sleazy, and certainly NOT RECOMMENDED for playing out with, but you will at least be able to play your amp at home at moderate SPL until you have the $$$ to get a decent cabinet. Other than that P. Diezel is absolutely correct in the fact that you will not get the full sound out of the amp from a combo speaker. Also, if the speaker is of relatively low wattage, you'll run the risk of blowing the speaker if you play the amp loud.
I personally like to keep the wattage of my cabs at least double the rated wattage of the amp. The reason being for this (If you don't know already) is that tube amps are rated for the amount of clean wattage that they produce. When you start pushing the power amp of a guitar amp into heavy overdrive where it's clipping out and compressing, you are essentially getting twice the rated clean wattage out of the amp.
So, essentially, an amp that is rated from 90 to 140 watts of output power, is actually pushing between 180 to 280 watts when it's being played hard. A single 100 watt speaker will not take this kind of abuse for very long, and you will either burn out the voice coil, or damage the moving parts of the speaker by cone overexcursion, and perhaps hanging the voice coil on the motor assembly.
When you get your new cab, plug the old cable back into the Mesa, and play away on either amp.

so with a herbert that is 180W, which cab would you suggest?
