[font=trebuchet ms]Ach, that's a sad, sad, thing. A guitarist who doesn't have intimate knowledge of his gear is like a painter who doesn't know which end of the pencil to sketch with!

As I recall (please understand that 'the Marshall sound' holds no allure for me, so I have not spent much time using their gear), the 1960 cabs have a Stereo/Mono switch on the back, and two jacks. In Mono mode, all four of the 16 Ohm speakers are connected together. One jack gives all-parallel connection for a total cab impedance of 4 Ohms. The other jack gives Parallel-Series connection for a net impedance of 16 Ohms. Either jack will work happily with your amp, provided that you select the matching output setting.

In Stereo mode, the four speakers are split up into two pairs of parallel-connected speakers, with each pair presenting an 8 Ohm load. This setting would allow two separate amps to each drive two of the four speakers in the cab, again provided that their outputs are matched to the load (8 Ohms, in this case).[/font]
