Re: How do I take the ohm rating of a speaker cab
Stick a cable in the jack and place your negative lead on the sleeve and your positive to the tip at the opposite end of the cable...Set your ohm meter so it reads in the range of 4 to 6 ohms...An 8 ohm speaker normally reads around 6 ohms...A 4 ohm reads around 2 and if it's a 16 ohm it'll read double digits in the range of 13 to 14 ohms...You don't need to take your cab apart by doing it this way!
So one end of the cable is plugged into the cab and you take your readings from the tip and sleeve of the opposite end of the cable...

No...You'd have to measure the winding taps at the output transformer wires inside the amp,plus you'd have to unsolder the wires(bad idea).....Can you get a manual for that amp maybe?
Does your head have an impedence switch on the back or just a jack or jacks?

It's just jacks. I'll post a thread specifically about this.
Thanks for the help.

Resistance is not the same thing as impedance. You can measure the resistance of speakers in a cab... and it is usually safe to round up to the nearest standard impedance value.
The resistance of coil windings on the output transformer are really too small to measure and try to guess at an output impedance.
